Ann Shumelda Okerson (born c. 1950) is an American librarian and expert on the licensing of electronic resources and the place of digital technologies in academic and research libraries.

Inspired by friends who were librarians, she switched to UC Berkeley's library science program and earned her MLS.

[2] At Yale, in 1996, she organized and for fifteen years ran the Northeast Research Libraries consortium (NERL), a group of thirty large research libraries (and over 100 smaller affiliates) that negotiates licenses for electronic information and engages in other forms of cooperative activity.

[3] Its extensive annotations and links are complemented by Liblicense-l, an international, moderated online discussion list to which some 5,500 librarians, publishers, attorneys, students and other interested individuals subscribe.

In 1998, Okerson secured an additional grant that created the Liblicense software, which enables users to generate a customized license using standard language options.

[6] In 1992, she wrote the synopsis chapter of the Andrew W. Mellon Foundation study University Libraries and Scholarly Communication.

[7] Also at ARL, she created and published five editions of the standard Directory of Electronic Journals, Newsletters and Academic Discussion Lists (1991–1995).
