Here's an excerpt from the press release:
With support from the Institute of Museum and Library Services, The Andrew W. Mellon Foundation and the Alfred P. Sloan Foundation, Dr. Cohen leads the development of the free, open-source Zotero (http://zotero.org) software for managing and sharing research sources. Zotero is currently implemented as a set of Web browser and word processor plug-ins that can synchronize citations and other information with a public server, which also serves as a social network and discovery platform for fellow researchers. Work is currently underway to develop a stand-alone implementation of Zotero for Windows, Linux and Macintosh operating systems as well as plug-ins for a broader range of Web browsers.
Cohen's scholarship includes the exploration of digital humanities and pursuing new ways to collect and preserve history on the Web. He has directed several archival projects, including the September 11 Digital Archive, ECHO: Exploring & Collecting History Online, and the Hurricane Digital Memory Bank: Preserving the Stories of Katrina, Rita, and Wilma. Cohen is the author of four books and has delivered dozens of papers and featured presentations at venues of interest to library technologists.
