There is growing interest in making academic books open access (OA), with the number of OA books increasing each year along with the introduction of additional funder mandates. However, limited awareness amongst authors as well as a lack of understanding and common misconceptions about licensing and quality, form barriers in the transition to OA for books. Within the context of open scholarship this calls for an open resource that is easy to use, kept up-to-date and relevant for researchers and research support worldwide. This has resulted in the concept of an Open Access Books Toolkit: making it easy for authors to find the information they need to publish their research as an open access book. The toolkit has been recently launched, and will be further developed over time with new resources based on user feedback.
