The present work uses a large-scale survey to study the users of two prominent social reference managers-Mendeley and Zotero.  Results show strong differences between platforms: Mendeley users are younger and more gender-balanced; Zotero users are more engaged in social media and more likely to come from the social sciences and humanities.  Zotero users are more likely to use the platform's search functions and to organize their libraries, while Mendeley users are more likely to take advantage of some of the discovery and networking features-such as browsing papers and groups and connecting with other users.
