WILIS 3 builds on previous WILIS studies by focusing on a collaborative approach to data sharing. The major aims of WILIS 3 are to: create publicly accessible de-identified datasets from WILIS 1 and 2; develop an interactive program-specific data system to enable LIS programs to explore their own data and benchmark with other programs; and produce a data archiving toolkit that can be used by other researchers. By documenting the process of data archiving, the products of WILIS 3 will serve as a model for other IMLS grantees to share their data, potentially increasing IMLS’s return on investment.
