# OAWeek2021: tub.torials – a review of thoughts, ideas, and materials on openness in science, research, and teaching

In April 2019, the tub. launched the HOOU project (Hamburg Open Online University) tub.torials. The goal: to contribute a small part to more exchange on and about openness in science, research and teaching. The term „tub.torials“ is composed of the abbreviation of the University Library of the Hamburg University of Technology (tub.) and the term „tutorials“ (a kind of instruction manual that explains topics, processes and functions in various forms such as text, film or other formats). Part of the project was a blog offering that will continue to provide regular contributions from the entire life cycle of scientific communication after the project ends in December 2020.

Introductory videos, tip collections and guest posts

Various open educational materials have been shared here over the past three calendar years. These include small collections of tips (e.g. tips for the start of the semester) as well as insights into ideas, experiences, events attended and workflows in everyday work via individual contributions (e.g. to Digitaltag 2021 and stARTcamp 2021) as well as formats such as monthly notes.

On the other hand, first steps with open applications (among others an introduction to Zotero, video recording with OBS or video recording with Shotcut) and insights into – from the tub. – offered events such as the bachelor seminar „Scientific Work“ were shared. The latter was often the inspiration for educational materials such as the Open Science Umbrella or a questionnaire to examine one’s own writing habits.

Looking back, the #Notizschreibwochen2020 series of articles was particularly exciting, in which guest authors from different areas of teaching, learning, science, and research shared their own methods and approaches to note-taking. Also very enriching: the many individual impressions and perspectives of students on topics such as the first online semester at the university or the topics of digitization and sustainability.

One of the highlights of 2021 will certainly be the Open Access publication „More than 77 tips for scientific work“, for which it was possible to build on experiences of the HOS project (Hamburg Open Science) Modern Publishing with applications such as GitLab and pandoc for the technical implementation.

Sharing is caring – what does the future hold?

What most of the publications on tub.torials have in common is mutual inspiration. Whether it’s guest posts with new perspectives on a topic, working together on texts, or exchanging ideas on publications. Whether it’s exchanging ideas and feedback via the comment function, at digital and analog events, by e-mail or via social media, the open interaction between us (and hopefully externally as well) always sparks new ideas. And so it is also a wish and goal of tub. in the future to offer an opportunity for exchange through the open sharing of experiences and impressions and to support courage and openness to try out new things. True to the motto: „It matters how we open knowledge“.

#OAWeek2021: It Matters How We Open Knowledge – ‚break chatter‘ as audio recording and transcript

Audio recording and transcript with Axel Dürkop (ITBH) and Florian Hagen (tub.)

On 28.10.2021 Axel Dürkop and Florian Hagen met for a „break chatter“ about Open Access Week 2021 and the partial motto “It matters how we open knowledge” via Zoom. The recording of the conversation is offered in this article unabridged as an audio file (German) as well as a “simplified” transcript (verbatim transcription, including omitting word duplications and adjusting punctuation to improve readability).

Some of the offerings, materials and services mentioned in the recording:


– Florian Hagen

Yes, to maybe set the context right away, let’s just get started now. A long time ago, we actually thought about recording a podcast on the topic of “It Matters How to Open Knowledge”. Before we start, I’d like to introduce myself: I’m Florian Hagen, I’m a specialist for Open Access and Open Education at the TUHH. Axel Dürkop and I often meet for a chat, and today we just thought we’d record our chat on this topic. And maybe you would like to introduce yourself to Axel?

– Axel Dürkop

Yes, thank you, I am Axel Dürkop. I work across the street at the TU Hamburg as a scientific consultant for technical development and conception for the Hamburg Open Online University at the TU Hamburg. And that’s how we met. We can talk about it again in a moment. Exactly. Yes, shall we also say something about earlier? Decades ago, training and all that?

– Florian Hagen

You can do that, I have omitted it now.

– Axel Dürkop

Or I don’t have to say. Maybe later. Okay. Yeah, how did we meet?

– Florian Hagen

I think we met in 2018, when the Hackerspace events were still taking place at TU. And Thomas Hapke, my old boss, just sort of tucked me under his arm and took me to Hackerspace. He said, that’s a nice thing to do. And what the Hackerspace actually is, maybe you can say something about it for everyone.

– Axel Dürkop

Yeah, that’s right. So the Hackerspace was… I don’t even know when we started it. Right now it’s dormant, which was partly due to the pandemic, because it actually consists of… so the fun comes from meeting, really meeting each other. We had done quite a lot of stuff in 2015 as part of the Hamburg Open Online University, which we also call HOOU for short, which we knew very well how to do in a small group and it was very innovative.

– Axel Dürkop

And it’s still somehow the basis for the things that you and I have done together, for example. We can also say something about that in a moment. We then had the feeling that we would like to share this knowledge because we were just so excited about what we were doing. And we thought, “Let’s tell others and see if they think it’s so great, too.” And the hackerspace format is one that we didn’t invent ourselves, but hackspaces are more of an international movement where people say they want to have a self-determined space where they can tinker and hack.

– Axel Dürkop

And hacking is, in a positive sense, the creative use of technology. So, and we also offered that and met every Wednesday, for at least two years every Wednesday afternoon and did our work as always or tried things out. And when other people came, we talked about technology and said what we were working on, others said what they were working on, and thus actually exemplified a culture of sharing or practiced it with ourselves.

– Florian Hagen

From my perspective, of course, I can only agree with that. If I think back, I got a lot out of Hackerspace and I thought it was a great opportunity to come together from completely different disciplines and to exchange ideas on certain topics in a certain interdisciplinary way. So at that time, we also had the idea of our tub.orials blog… that is, a blog offering that is also about openness around science, research and teaching. And I’m still of the opinion, but I can’t remember exactly, that you put a flea in my ear at some point … that the blog is a good thing first of all as a means of communication. But it would be even cooler to somehow make it even more sustainable and reusable. So I think that somehow the idea arose from this exchange within Hackerspace. We always have a license notice at the bottom, because the things are all openly licensed and there we link the material for reuse and also the texts themselves are offered in marketdown format.

– Florian Hagen

And I think that’s still a really cool thing and I’ve heard at least occasionally from people who just take out the texts again, because it’s often the case that you can’t get something like that out of a blog so easily.

– Axel Dürkop

Yes, so I can’t claim this authorship for myself now as you just attributed it to me. But it may well be, because I was extremely enthusiastic about the possibilities of GitLab and GitHub then and still am today. That was just also what we were trying to kind of share there. That what we learned there. We got GitLab up and running at TU in 2015, in a framework that was supposed to make it possible for everyone to work with GitLab, and now it is. And my approach to it was not so much to use it for software development, but for the development of texts and just open educational materials, which can also be programmed, of course. But I still have great fun working with this collaboration platform and web-based texts or media. And what you’re doing there with the blog is also depositing things in Git Lab so that you can download them there. And for me, that’s what I’ve already said.

– Axel Dürkop

I think it’s a great example of simply providing access to knowledge, simply also in a technically simplified form. You don’t have to know anything about GitLab or Git if you want to take your texts. You just offer them again in other formats in a meaningful place for download, so that other people can somehow continue to work with it. And I think that’s great, because the 5-R of Wiley are, according to my observation, rarely followed through in the last consequence. Namely, they say, for example, here are the raw materials. So you don’t have to scrape this off the website, but I give it to you in such a way that you can continue working with it quickly. And I think that’s great with the blog you have.

– Florian Hagen

Yes, thank you again for your feedback. So basically… we are moving a bit in the context of the Hamburg Open Online University, the HOOU. The blog was created in this context and GitLab was also often used for various materials. Recently, I have to say, I don’t even remember when exactly it was, the stARTcamp online took place. And you also offered a session or a contribution on the topic of learning circles as part of the stARTcamp. And to be honest, I don’t really remember why I wasn’t there. Maybe I had offered another session at the same time or it was a different date. But could you explain again what these Learning Circles are all about?

– Axel Dürkop

Yes, very much so. I think I came across Learning Circles in 2015 when I started to get more involved with Open Educational Resources and sharing education or knowledge online. And I always found the Learning Circles, as they were developed by the Peer to Peer University, strikingly good. Because they identified what is still a fundamental problem today when we talk about open access or about the inequities in access to education. People often say that it’s on the web, let’s put it on the web, let’s put Creative Commons licenses on it, and then they assume that that’s enough. But I think that’s only a necessary condition, that it’s openly available, so to speak. Because if it wasn’t, there would be no need to talk further. So it’s necessary that it’s freely accessible, openly accessible, and that it can be reused. But it is not sufficient, because it has become clear in the context of digitization that many people do not necessarily use it to learn, despite this accessibility. And the idea of learning circles is that back then, people took Massive Open Online Courses that are freely accessible and learned together with them in learning circles.

– Axel Dürkop

And this idea has become very strong. It has become very popular in different countries. In Africa, too, it has developed in its own direction, but it’s very strong and people use it to acquire freely accessible content in a very self-determined way, and ever since I knew about it, I’ve always wanted to do that because I thought, “This is how it has to be,” so let’s take content from the web and let’s find didactic forms with which people can learn with it. And then I organized a Learning Circle together with Gabi Fahrenkrog and Sarah Politt from the Bücherhallen, and the topic was robotics and AI. And we not only learned together four times, four evenings, sorry, six evenings together, but we also published what we had compiled there as a small compendium of a curated collection of links at the end.

– Florian Hagen

However, this means that a Learning Circle is not just for individuals who say that they would like to learn something additional or simply adopt a different form of learning in social interaction with a group that I may not yet know. But that would also be something, so that’s how it sounded to me now, if I have a small team or a small group that perhaps also want to exchange ideas with other people on a certain topic, that this is also a possibility for a kind of team development or team building? Because we often talk about joint writing in other projects where we work together. So that would also be something of a team development aid or measure, so to speak?

– Axel Dürkop

That’s a good idea. I think that in some cases there is perhaps a working group or a learning group and they do it together. I think that’s the crucial thing about it, that in-house training or continuing education works best when it’s project-related and people do it together. That’s why I think what you’re proposing certainly makes sense. Especially because it is not related to Friday afternoon and Saturday and then certificate and then is learned. It’s more about saying that this is a work-related project that you work on and grow. For example, the Hackerspace and these contexts have given rise to various formats of continuing education programs at the TU over the years that I have reported on. These also bring the idea of sharing knowledge and experience, and not just my knowledge and experience, i.e. when I organize them. But what I find great is that others, who have perhaps already worked with it or have first experiences or even advanced experiences, also share them. In other words, it’s not about one person knowing and passing it on in the classic sense, but I think the great thing about it (also about the Learning Circles) is that “everybody is an expert”. It’s not about who has the most expertise and the most experience, but who perhaps also has the courage to articulate diverse perspectives on the topic and to rub shoulders with each other, and that simply creates new things. I think that’s great. And that was also the idea behind Hackerspace. That you don’t lecture others about what you know, but rather I’m excited about it, may I show you something. And then someone says, that’s great, but look what I’m doing. And then you say, “Okay, thanks,” and you go out and you’ve enriched each other. That’s great. That’s what that runs to. And so I also think what you’re suggesting is a great way to share knowledge within a company or university.

– Florian Hagen

Yeah, cool, thanks for the insight. When you just said Hackerspace again… As someone who has participated in it, it’s immediately apparent that some of the virtues of this Learning Circles approach have perhaps already taken place in an unplanned way. So, that people simply share among themselves and that they definitely take something with them. You can really see parallels there, without it having been planned that way at the time when the Hackerspace was started. So I think.

– Axel Dürkop

I don’t remember that exactly, it could be. It has parallels, of course. The parallel is: people just learn well in groups. That’s why – for example, if the motto of this year’s Open Access Week is “It Matters How to Open Knowledge” – then the “how” is precisely what needs to be emphasized. That’s what I was talking about earlier. It’s not enough that we put everything on the Internet. It’s the same with Open Data. That’s a nice thing, yes. But I have to know the context, I have to know how to get at it and what I can do with it. And that requires a certain expertise. And to gain this expertise, to get there… that is certainly also a very honorable educational mission of universities and perhaps also libraries to say “Ok, we build the bridges there”. That’s why this “how.” It’s not done with it being on the web. But it starts with. Ok, we’ve got something nice here, don’t you guys feel like and how can we help you. And that’s certainly the case with Hackerspace, but also with the Learning Circle. A connecting idea, just to see who is there and what does the individual person need and to help people find access to themselves for themselves.

– Florian Hagen

You’ve just mentioned it yourself, so perhaps one more question to conclude our little exchange. This year’s motto is “It Matters How to Open Knowledge” and we haven’t agreed on any questions beforehand. Listeners can’t see that right now, but you’re already looking very curious about what might come next. As I’ve said before, when we talk to each other, I actually take something away from every conversation. So you always put an idea in my head or point me to something, a material or something, which I always find inspiring in some way for me or for teaching and for my own learning. If you now think about “opening up” knowledge, are there any projects or materials from the fields of open science, open access or other openness movements that you find inspiring or simply worth a look if you are interested in them? Of course, reading recommendations are also welcome.

– Axel Dürkop

Reading recommendations I would have to think a bit longer now. I have a new topic that totally excites me. I’m just saying that now because I’m so excited myself right now and it’s sweeping me away. I don’t know if others find it so great. But I’ve always found… or lately, always I can’t say. But I’ve been watching alternatives to the traditional internet for about 4 years. I think that’s exciting right now. And there’s a whole bunch of stuff that I’m seeing there that’s emerging. Traditional internet or traditional web is what we know like that. Small server and we provide, for example, Open Educational Resources to download and have places where they are. There’s sort of traditionally the idea that we have servers and that’s also the problem that we have right now with big platforms. That they have simply become very powerful. That’s not yet the case in the OER context, it’s not a problem there. But I was interested in what this “peer to peer” actually is, because of course this is also and this is perhaps the connection to the peer to peer university… this peer to peer, so people among themselves without a mediating authority in the middle. What kind of technical systems does that give off. And there is the Fediverse, the federated network, which actually dispenses with central servers as far as possible, but works in a decentralized way. There are no middle men or middle women, so to speak. I find that very exciting right now, and there are very interesting technical developments that I’m currently trying to check for their usefulness for sharing. Is it too complicated? Is it resilient? That’s one thing that comes to my mind right now. I don’t know if that’s as exciting to others. But one piece of software I’m experimenting with right now in a course is the Beaker Browser, which allows you to instantly set up a peer to peer network of educational materials with each other without a server. What I find exciting is the Interplanetary File System, which unfortunately sounds totally silly when you say it… But, it’s gotten very big and it intends to do exactly the same thing, which is share whatever without a central cluster. For me, that would be knowledge or information set up. I think that’s very cool, I’m very excited about that right now. I want to check that for teaching and the openness movement in the area of open science and open education.

– Florian Hagen

Cool. So I haven’t heard of all or almost all of those things. With the system that you mentioned last. I was kind of stuck on “The Hitchhiker’s Guide to the Galaxy”. I’ll definitely take a look at that. It’s actually a pity that there’s currently no such possibility that you can simply meet on site and work on your own ideas and then in this framework, as it was for example also at Hackerspace, just have a quick look, what is that actually. Nevertheless, I’ll be happy to take a look at that. And that brings us more or less to the end of our short exchange.

– Axel Dürkop

Wait a minute. You were kind enough to ask me what’s on my mind right now. But now you tell me, what is it that’s getting you excited right now?

– Florian Hagen

What is it that gets me excited about Open Science, Open Access, Open Education, Openness? There are actually quite a few things that are floating around in my head. At the moment I’m doing this in my course… Well, we have a course on “Scientific Work” for Bachelor students at the TU. And I often sit down again after the lectures, because the students always have a lot of input, from which I also take a lot and learn. And I still try to capture something like that in script form and share that with everyone. And often that happens through collaborative writing tools like HedgeDoc, which I think used to be CodiMd. And I feel the need sometimes that at the end of the semester, I would just like to have all these scripts that I’ve written, I’d like to bang those in somewhere so that I could just have a cohesive PDF generated from those scripts. So sort of a little brochure at the end of the semester. I have already been told by students that it is very pleasant to have everything collected again. Of course you can also save the links via literature management or other possibilities. But often it is still the case that you like to print something out and put your own comments and annotations on a normal PDF. That’s something that came up again today in a lecture. I think I’ve mentioned this before, that I had thought about how you could implement this somehow, so that the additional effort is not so great. But that you get a stable format or a digital artifact at the end. That’s what I’m interested in right now.

– Axel Dürkop

Yes, I find that very exciting. I have already experimented with it. I find HedgeDoc just as exciting and indispensable in the meantime for many things that I do. And since you can export them wonderfully, not only in the social form of HedgeDoc learning, but you can also use them technically. So everybody can take it for their own purposes, similar to what you mentioned for your blog as well. And yeah, what we need then is an automated form of downloading and aggregating to create a compendium like that. Yeah, let’s get together on that.

– Florian Hagen

Look, here we are again with a topic we can work on together.

– Axel Dürkop

Absolutely right, very nice.

– Florian Hagen

Very cool. What I actually wanted to say just now, first of all, thank you for finding the time today so that we can just talk about it again as part of Open Access Week. And we’ll probably see each other again in the next few days in some meeting. But I also hope that the one or the other who listened to this recording now, that there was also something interesting to take away from our chat. Just like I always do when we exchange ideas.

– Axel Dürkop

Yes, thank you very much for the initiative that we met here. I think your questions about the hackerspace and our conversation about it made it clear once again how important it actually is. So you and I now also have a concrete plan of what we have to do now. That we now meet again and that this format simply gets going again, now that it is hopefully possible to meet again. We have face-to-face teaching again, it works. That’s why we should perhaps take this as a prelude to thinking about whether we should first revive this possibility of sharing knowledge in our small project, which we had now considered, but then perhaps in a wider circle.

– Florian Hagen

I would definitely be there.

#OAWeek2021: How do I fund my journal article?

Are you planning to publish in a journal and don’t know what funding options are possible? The TU Library can provide funding for articles in a number of ways. Our Publishing Fund enables the financing of articles in pure Open Access journals (Gold OA). If the criteria for funding are met, TU members can submit a funding request through the OA website. Furthermore, TUHH’s participation in the DEAL agreement allows OA publishing in hybrid and gold journals published by SpringerNature and Wiley.

We have illustrated in a flowchart which questions you need to ask to find out whether the criteria for funding are met and what the workflow looks like after a funding application has been approved. For optimal display, the “Fullscreen” option (top right) should be selected within the H5P element.

If you have any questions about Open Access and funding an article, please feel free to write to us at openaccess@tuhh.de.

What have we funded in 2020?

As part of the OpenAPC initiative, all APC payments made by the TU Library are published as Open Data. This provides an overview of the costs related to the TUHH, at the same time showing to which publishers the money flowed:

In 2020, the tub. publication fund financed pure gold open access articles with a total amount of €65,157. There are also articles with the publishers SpringerNature and Wiley that run via the DEAL contract.

OAWeek2021: Basics on Open Access at TUHH – Glossary and open, virtual Q&A session

Open access is understood to mean free access to quality-assured scientific information and other materials. All people worldwide have unrestricted, free access to OA publications. The TUHH has supported the Open Access movement and its goals for many years. With TORE (formerly tub.dok), there has been an OA repository since 2002, which now enables the storage of research data and functions as a research information system. The TU is a signatory of the “Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities” of 2003 and reached another milestone with the establishment of a publication fund in 2013. This fund supports publications by young TU scientists. With the unanimous adoption of the openTUHH Policy in the Academic Senate of the TUHH on 26.09.2018, the topic of openness in research and teaching at the university received additional support. The policy emerged from the Hamburg Open Science (HOS) and Hamburg Open Online University (HOOU) projects. The goal: to further promote digital cultural change at the university (More on HOOU and HOS projects of tub. on the TU Library project page). For these efforts around openness and further open access services, the tub. 2020 was awarded as an “open library“.

Open Access Glossary

However, especially for newcomers and outsiders, there are always many questions surrounding OA and the numerous fields of development, such as “What is meant by green OA?”, “What are the differences between gold and hybrid journals?” or “Why shouldn’t people publish in closed access?” In order to make Open Access and its advantages more accessible to as many interested parties as possible, the Open Access team has compiled a small glossary. The compilation is based on questions around Open Access terminology, which is a frequent topic in consultation scenarios:


“Article Processing Charges (APCs) are publication fees that authors pay to journals for publishing their articles in open access. Not all OA journals charge APCs. This fee model is intended to reflect the time and effort spent by publishers on quality assurance, processing and publication of the publications. “Processing charges” also exist in the area of OA monographs (see BPC).


arXiv is a preprint document server – operated by Cornell University – for physics, mathematics, computer science, quantitative biology, quantitative finance, statistics, electrical engineering and systems science, and economics.


“Book Processing Charges” (BPC) are publication fees that authors pay to publishers for the open access publication of books (monograph or edited volume). There are also “Book Chapter Processing Charges” (BCPC).


Citavi is a windows-based standalone literature management program, which is characterized by comprehensive functionality and ease of use and can be used in research and teaching. The TUHH provides access to Citavi to all members and thus also to the students of the TUHH within the framework of a Campuslizenz.

Closed Access

Closed access means that scientific information (e.g. in articles) can only be viewed by paying a fee. These costs are taken over by university libraries or also the interested readers. By choosing closed access, authors waive their own exclusive rights of use and exploitation. From now on, these rights are held by the publisher. Authors can therefore no longer decide on the further use of their own research results.

Corresponding author

The Corresponding Author is the main contact person for questions regarding the article during and after the publication process. In the case of funding by the TU Library, a key criterion is that the Corresponding Author identifies him/herself in accordance with the TU Affiliation Policy and, in the case of an affiliation with multiple institutions, that the TUHH is named first.

Creative Commons

Creative Commons licenses (CC licenses) are standard licenses that make it relatively easy to grant interested parties rights to use the respective works. Through these licenses, free works are created. The license itself functions according to the modular principle. The recommendation for Open Access via the tub. is currently the standard CC BY 4.0 (Attribution). For more on CC licenses, see here.


Under the project name DEAL, the HRK is negotiating Germany-wide transformation agreements with the major STEM journal publishers (Elsevier, Springer Nature, and Wiley) on behalf of the Alliance of Science Organizations. Contracts could be concluded with the publisher Wiley in 2019 as well as with SpringerNature in early 2020. The DEAL contract allows TUHH members to publish TU Hamburg publications in the journals of these publishers in open access and to access the journal offerings of both publishers for reading. Since 2021, the DEAL contract with SpringerNature also includes the renowned Nature Research journals for the first time.


The DOAB (Directory of Open Access Books) is a cross-disciplinary directory of scholarly e-books that are and have been published with an open access license. DOAB is also included as a resource in our tub.find catalog.


The DOAJ (Directory of Open Access Journals) can be used to search quality-checked open access journals and their articles. DOAJ is also included as a resource in our tub.find catalog.


The DOI (Digital Object Identifier) is an alphanumeric permanent identifier of a publication and serves to identify it unambiguously in the network and to make it citable. Consisting of two parts, it is made up of the publisher number and a character string that identifies the individual digital object.

Double Dipping

The term ‘‘double dipping’’ has a negative connotation. It refers to the hybrid journal business model (see also Hybrid Journal), in which, among other things, library budgets are charged multiple times. First, because fees are taken for access to a journal (subscription fees), and second, because publication fees (see APC) are taken for articles that can thus appear open access via hybrid journals.

embargo period

The embargo period is a possible publisher requirement for secondary publication as Open Access. This describes the period of time that authors must wait before their article may be made available on an institutional repository, for example. The length of the embargo period depends on the publisher and the journal in question. It can range from 6 to 24 months. The specifications of the individual publishers can be found via the project SHERPA/RoMEO.

First publication

see Golden Path

Golden Way

The Golden Path stands for the first publication of a scientific article in a pure Open Access journal. These undergo the same quality assurance processes as conventional works, e.g. in the form of peer review or editorial review. Pure open access journals are also characterized by the fact that the article is immediately freely available and thus immediately usable by everyone. For the publication costs incurred, which usually have to be paid by the author, funding can be applied for under certain conditions via the Publication Fund of the tub.

Green Way

The Green Way is the second publication as Open Access. This means making previously published papers available in repositories such as TUHH Open Research (TORE). There are possible publisher requirements to consider for second publication. Most scientific publishers allow delayed publication of the postprint or preprint on a repository of the own institution. Detailed information on the specifications of individual publishers is provided by the project SHERPA/RoMEO.

Hybrid Open Access

Hybrid open access is a way of making individual articles published in subscription journals additionally freely available in return for a publication charge (APC).

Hybrid Journal

The term “hybrid journal” refers to subscription journals in which individual articles can be published as Open Access in return for payment. The journal consists of closed and open access articles and is therefore not a pure open access journal. This model is not without controversy, as it results in double payment of subscription and publication fees to publishers.

Open Access Monitor

The Open Access Monitor was developed by the Central Library of the Research Center Jülich as part of a project and with funding from the German Federal Ministry of Education and Research. The OAM records the publication volume of German academic institutions in scientific journals, which can then be used to perform analyses of subscription and publication output.


Opt-out means that authors decide against Open Access and thus transfer exclusive rights to publishers. The further use of their own work is restricted by this decision. An article is therefore no longer visible without restriction to all interested parties worldwide. Institutions must pay individually for the article in question or subscribe to the journal in question so that relatives can access these research results (see also closed access). The choice of Ops-out also does not lead to a cost reduction for TUHH.


ORCID stands for “Open Researcher & Contributor iD”. With this iD, scientists can be clearly linked to their research activities and results, even if they have the same name or different spellings. The ORCID iD is used internationally by publishers and organizations in the scientific field and is already integrated in large systems such as Web of Science, CrossRef or Scopus as well as in many journals. The ORCID id can be linked to the contact database of the TUHH as well as to the publications in TORE.


A paywall is a payment barrier or access barrier for online content. Access to this content is subject to a fee, which means that users can only access these publishing offerings after paying a fee or taking out a subscription.

peer review

The peer review process serves to ensure the quality of a scientific paper before it is published. An independent reviewer from the same field evaluates the work. For more information see our blog Wissenschaftliches Arbeiten.


This is a scientific text that has already gone through the review process and has been accepted for publication in a journal. A distinction can be made between two forms of postprint: a postprint that is completely identical to the publisher’s publication in terms of both content and form (e.g. layout), and a postprint that is identical in terms of content but has formal deviations.

Predatory publishing

Predatory publishing or Predatory Journals, differ from serious journals, e.g., in the fact that authors are to be led to the paid submission of manuscripts via intrusive spam mails. During the solicitation, short (mostly unrealistic) peer review processes are advertised, which do not take place in the end. On the pages of the respective providers, there are inconsistencies such as contact options via e-mail addresses that do not look very professional, texts that are copied together and contain typing and printing errors, and little transparency regarding publication procedures and contract information. The web service Think – Check – Submit offers good assistance in selecting the “right” magazine.


In contrast to the postprint, the preprint is all versions of a scientific publication that were written before the peer review process. These have therefore not yet gone through the peer review process.


A repository is a document server for publishing and archiving electronic publications. Uploaded documents are given a unique identifier (e.g. DOI) so that they can be found and cited. TUHH’s repository is TUHH Open Research (TORE).

Many publishers and journals allow additional publication by the authors as Open Access under certain conditions. The so-called SHERPA/Romeo list is intended to help make the publishers’ standard conditions for open access publications more transparent for authors. Information such as possible embargo periods, licensing conditions or article versions can be found here.


TUHH Open Research (TORE) is the repository for open access publications (formerly tub.dok) and research data as well as the research information system of the Hamburg University of Technology (TUHH). Here, freely available publications by members of the TUHH are made available in full text. The spectrum includes journal articles, conference papers and reports as well as dissertations written at the TUHH.


Zotero is a literature management application that helps to collect and organize literature and, if necessary, to integrate the respective literature into one’s own writing projects. It is open source software that runs on all major operating systems. A introduction in text and video form is available on our tub.torials blog.

#OAWeek2021 Open Access Consulting at the TUHH

„TUHH members are explicitly encouraged and helped to make their scientific findings in research and teaching publicly available and to try out new forms of open collaboration.“

Open Access Policy TUHH

When the Executive Board of the TUHH publicly named Open Access as a strategic goal in March 2013, it was at the same time aware that this goal could only be achieved with concrete support. Therefore, an official OA Representative was appointed at the TUHH. Since then, this task has been performed by the director of the library.

#OAWeek2021 Why I support Open Science

Guest article by Prof. Dr.-Ing. Tobias Knopp* , Institute for Biomedical Imaging

Openness and science have been closely connected since the beginning of mankind. The goal of science is to discover new insights based on existing knowledge. Accordingly, access to knowledge is absolutely essential to avoid having to reinvent the wheel over and over again. Despite this obvious connection, openness does not seem to be a given in all branches of science. This is also evident from the fact that the term Open Science had to be established in the first place.

#OAWeek2021: Welcome to Open Access Week 2021

This year, Open Access Week will take place from October 25 to 31, 2021. Under the motto „It Matters How We Open Knowledge: Building Structural Equity“, institutions are promoting open access to scientific information with events and activities. TUHH is also participating with the support of the TU Library.

Open Policy der TUHH

Hamburg University of Technology is committed by Policy of Openness in Research and Teaching to quality, transparency, participation and international cooperation in research and teaching and to networking within the University and with partners in science, business and politics. It thereby embraces the vision of the university as a place for trans-disciplinary dialog where work on solutions to societal challenges and basic research take place in open exchange with work, testing and research being undertaken jointly.

„If you think about science in its elementary structure, an open exchange of knowledge, findings, and ideas is one of the main drivers of innovation.“

Andreas Timm-Giel, President TUHH

Open Science

Open Science is a culture change in scientific methodology and communication. It means that communication, networking and sharing information among scientists and between scientists and civil society can be shaped and promoted more openly and more effectively by means of digital tools. It is accompanied by the requirement to make access to scientific publications, research data and scientific software barrier-free from the financial, technical and legal perspectives. The aim of this is to improve scientific processes, to enhance transparency and ways to assure the quality of scientific work by improving the provision of information and to increase scientific transfer and innovation in business and society that is based on scientific findings

„I also believe that the shift to open science, meaning sharing our findings and scientific results openly according to the Fair principles, is a great advantage. Only if other researchers can access our results easily including measurement data and source code, they will easily reference our work and can openly discuss on improvements with us with our researchers.“

Andreas Timm-Giel, President TUHH

TUHH Research Data Policy

The sustainable preservation and provision of research data contributes to the traceability and quality of scientific work and opens up important connection possibilities for further research. For this reason, the Academic Senate of the TUHH adopted the Guidelines for Handling Research Data at the TU Hamburg in May 2021.

According to the FAIR principles, research data must be findable, accessible, interoperable and reusable. Responsible handling of research data throughout the entire life cycle is an indispensable part of good scientific practice. This has now been explicitly emphasized for the TUHH with its own research data policy.
