The importance of open access (OA) advocacy is well-documented in the literature of academic librarianship, but previous research shows that librarians' OA behaviors are less conclusive. This article compares the self-archiving practices of music librarians and musicologists to see how librarians rank in OA adoption. Availability of articles published from 2013 to 2017 in six green OA journals in music librarianship and musicology indicates a need for continued advocacy and enhanced understanding of OA policies and opportunities.
