Chosen from more than 300 nominations, the 50 individuals and one organization named 2015 Movers & Shakers are passionate about what they do, whether it is advocating for literacy and diversity, serving the underserved or spreading and sharing technology.

This year’s Movers & Shakers are profiled in the March 15 issue of Library Journal, and those profiles will be posted in an online version, sponsored by OCLC and Boopsie, rolling out this week, one group at a time.
