There are currently 3276 academic peer-reviewed books from 110 publishers in the Directory of Open Access Books (DOAB). DOAB is a service of OAPEN Foundation, a non-profit foundation dedicated to Open Access publishing of academic books based at the National Library in The Hague.
“The primary aim of DOAB is to increase discoverability of Open Access books. Academic publishers are invited to provide metadata of their Open Access books to DOAB. Metadata will be harvestable in order to maximize dissemination, visibility and impact. Aggregators can integrate the records in their commercial services and libraries can integrate the directory into their online catalogues, helping scholars and students to discover the books. The directory is open to all publishers who publish academic, peer reviewed books in Open Access”
In order to have their books indexed in DOAB publishers must meet the requirements for both Open Access and peer review. DOAB’s monographs cover a broad range of subjects and disciplinary areas. To browse subjects covered click here.
