The aim of this study is to investigate how efficiently the full text accessible electronic resources of Hacettepe University Libraries are used. For this purpose the usage data obtained from COUNTER Software regarding the electronic databases to which Hacettepe University Libraries subscribed in 2007 were examined.

Some 1,575 journals appear in more than one database and 2,912 journals were never used. A great part of the core journals identified by the Bradford Law are included in the ScienceDirect database.
