The Librarians Association of the University of California, Berkeley Committee on Diversity (CoD) has existed for at least 20 years; recent years saw a waning in its activities. A task force convened in 2014 to revise the CoD’s charge, hoping to revitalize the group, and effect change in the diversity of professional librarians. The CoD has since sponsored several events, and reinstated a librarian/staff mentoring program. While the CoD’s re-invigoration has received praise, work remains. UCB librarian diversity (particularly in terms of numbers from underrepresented minorities) remains low. Perhaps the CoD’s work toward culture change and a more supportive climate may be conducive to a future demographic shift.
