OCLC has mined data collected through use of OCLC resource sharing services to provide member libraries with lists of the most-requested monographs and journal titles requested through the service. The lists below show the most-requested monographs (books) and journal titles (articles) requested via OCLC Resource Sharing over a one-year period, from 1 July 2012 through 30 June 2013.
