The OA effect: How does open access affect the usage of scholarly books? | white paper | Springer Nature

"This report presents the first major comparative analysis of usage data for OA and non-OA scholarly books, and provides an informed view of how a book benefits from OA publication. It also highlights the challenges involved in measuring the impact of OA on scholarly books and suggests that there is much to do across the whole scholarly communications network in supporting authors and their funders. 

Part 1 of the report presents the findings of the quantitative analysis. The average performance of OA books, as measured by usage, citations and online mentions, was compared to the average performance of non-OA titles. 

Part 2 presents feedback from authors and funders who were interviewed about their experiences and perceptions of OA book publishing with Springer Nature. Interviews focused on: the impact of OA on books; OA book metrics that are of most relevance to authors and funders; and authors’ and funders’ expectations and experiences of, as well as motivations for, OA book publishing. ..."
