The Main Library University of Zurich supports its researchers financially when publishing with open access. This means that the library keeps various membership agreements with publishers that enable authors to publish at reduced rate in open access journals.
In addition the library also maintains an open publishing fund for open access publications in the humanities and social sciences. In this manner all disciplines can be considered with financial support.
An overview of all memberships and about the publishing fund for humanities and social sciences you can find here. This presentation was held within the Open Access 2015 on October 20th, 2015.
