Open access is when academic research is made freely available for anyone to read and re-use. As with open access journals, there are different business models for funding open-access books, including publication charges, institutional support, library publishing, and consortium models. OECD Publishing uses a freemium model by making its books available online in HTML with the option to purchase a print copy. There is some evidence that making electronic editions of books open access can increase sales of the print edition.
While open access to journal articles has become very common, with 50% of articles published in 2011 available as open access, open access to books has not yet seen as much uptake. However, there are dedicated open-access book publishers such as Open Book Publishers and others who publish both books and journals, such as Open Humanities Press. A report released in 2015 by the UK's main funding body for research, the Higher Education Funding Council for England, states the importance of open access monographs: "Monographs are a vitally important and distinctive vehicle for research communication, and must be sustained in any moves to open access."
The Open Access Publishing in European Networks (OAPEN) project provides access to hundreds of peer-reviewed academic books, mainly in the humanities and social sciences. It also proves a directory of open access works via Directory of Open Access Books (DOAB).
