The eBooks Study Group is a 501(c)(4) non-profit organization led by a self-assembled, largely volunteer, small group of librarians, attorneys, and library advocates from various non-profit organizations such as Library Futures, EveryLibrary, and ReadersFirst.
The model legislation was developed by Kyle K. Courtney, a copyright lawyer and librarian, and co-founder of Library Futures.
(Library Futures, a separate entity, is a project of the New York University Engelberg Center on Innovation Law & Policy. Their funding is publicly available.)
