Welcome to ADAT

The Academic Database Assessment Tool (ADAT) was designed to help libraries make informed decisions about investments in major bibliographic and full-text databases. It allows users to compare database title holdings, as well as key features of database and eBook content platforms.

JISC Collections initiated ADAT in 2006. Since its creation, ADAT was managed by DataSalon, a commercial service provider, under the auspices of JISC. DataSalon collected and aggregated source data from various providers and merged that data into a single database.

In November 2012, ADAT moved to a new home at the Center for Research Libraries (CRL), with a newly developed interface. ADAT is now a joint project supported by both CRL and JISC Collections (see the About page for more information).
