This grant provides support for the expansion of a successful postdoctoral fellowship program run by the Council on Library and Information Resources (CLIR). The program aims to help academic libraries provide a new set of services that support data- and computation-intensive research through funding postdoctoral fellows devoted to data management and curation in the natural and social sciences. Grant funds will provide salary support to two cohorts of fellows (ten in 2013 and 12 in 2014) as well as various support and training activities such as professional training, travel, and networking with other data curation professionals.
