The TUHH Library participates in funding open access books from the International Water Association (IWA).

IWA Publishing’s e-books cover topics from all areas of water treatment and wastewater purification.

These are accessible through the Open Research Library of the open access service provider Knowledge Unlatched.

In Knowledge Unlatched’s funding model, libraries jointly fund books from publishers to make them open access. If not enough libraries come together to support the project, only some of the titles will be made openly accessible. However, the participating institutions will in any case receive free and permanent access even to the titles that are not later openly accessible.
