Birgit Schmidt, Geschäftsmodelle des Open Access-Publizierens: Welche Perspektiven bieten sich hier für Bibliotheken?  A preprint.  (Thanks to medinfo.)  In German but with this English-language abstract:

Today, libraries serve as places where competences in dealing with the origin and dissemination of information are in demand. Once the document is ready for publication academic authors may opt out of a range of new publishing models. Increasingly, libraries foster Open Access. In this article Open Access business models are reflected on services and interests of libraries. Moreover, some development trends are identified.
