Online library and publication platform

OAPEN promotes and supports the transition to open access for academic books by providing open infrastructure services to stakeholders in scholarly communication. We work with publishers to build a quality-controlled collection of open access books and provide services for publishers, libraries, and research funders in the areas of hosting, deposit, quality assurance, dissemination, and digital preservation.

SCOSS supports OAPEN and DOAB

SCOSS, the Global Sustainability Coalition for Open Science Services, selected OAPEN and DOAB as vital infrastructures to support the transition of monographs and book chapters to open access models. SCOSS provides a coordinated cost-sharing framework for enabling the broader OA and OS community to support the non-commercial services on which it depends. SCOSS encourages the community to support OAPEN and DOAB in its second funding cycle.


The OAPEN Deposit Service supports open access policies of research funders and practitioners (research institutions, universities and their libraries). The Deposit Service provides an institutional uploading service for researchers and publishers. The OAPEN Library is adapted to the specific demands for academic books, and deploys the metadata standards, classification schemes and distribution channels for academic books.


Libraries need to know which openly licensed books are published by reputable academic publishers. Publishers of OA books need to become part of existing library discovery systems to reach their target audiences. OAPEN provides freely available harvesting options and daily metadata feeds in various formats to libraries and library suppliers, to disseminate the OAPEN collection.


Making books freely available on the web is only helpful if they are made discoverable. The OAPEN Library is optimised for search engines and is indexed by Google Scholar. In addition to disseminating metadata to Libraries and Library discovery systems, all books with an open license are indexed in the Directory of Open Access Books (DOAB).


Growing recognition of the value of open access books

We are pleased to share a number of recent initiatives that underline the growing recognition of the value of open access books and of DOAB as a primary resource for discovery and quality assurance.
