Many initiatives have been undertaken to make journal articles and other content available through open access. For many disciplines, books are equally important as a source of published information when conducting research especially in humanities and social sciences. Authors of academic book chapters could choose gold open access wherein they pay a fee and the publisher makes the chapter freely available. Another alternative is green open access, wherein an author would place a version of the chapter in an open access repository.
The results from De Gruyter Open Author survey reveal some interesting statistics. Of the 99 authors who wrote toll access book chapters, 55.5% self-archived their chapters. These authors were of the view that the public should have access to the research. Another 5% used green OA because they wanted to support those in the low-income countries. This shows that most authors support open access for ethical reasons too.
