Jill Emery has published "How Green Is Our Valley?: Five-Year Study of Selected LIS Journals from Taylor & Francis for Green Deposit of Articles" in Insights.
Here's an excerpt:
This study reviews content from five different library and information science journals: Behavioral & Social Sciences Librarian, Collection Management, College & Undergraduate Libraries, Journal of Electronic Resources Librarianship and Journal of Library Administration over a five-year period from 2012–2016 to investigate the green deposit rate. Starting in 2011, Taylor & Francis, the publisher of these journals, waived the green deposit embargo for library and information science, heritage and archival content, which allows for immediate deposit of articles in these fields. The review looks at research articles and standing columns over the five years from these five journals to see if any articles were retrieved using the OA Button or through institutional repositories. Results indicate that less than a quarter of writers have chosen to make a green deposit of their articles in local or subject repositories. The discussion outlines some best practices to be undertaken by librarians, editors and Taylor & Francis to make this program more successful.
