Collection evaluation, particularly which of printed material, is only one aspect of library evaluation which regards both collection development and general assessment of library performance. Among several qualitative and quantitative methods we find the use factors approach based on information about library holdings, use of material and access to it, namely circulation data and interlibrary loan requests. These factors enable to determine parts of the collection which are heavily used or parts that are disproportionately developed compared to their use by patrons.
This case study aims at displaying subject distribution of filled ILL requests and the use of local collection of monographs (circulation data) compared to holdings data. We then look at how these distribution correlates with acquisitions and their subject distribution. Conclusions refer to the current use of local collection and to recommendations for rational collection development decisions. The research is based on holdings data, printed monographs usage data, access statistics (circulation and ILL data) and acquisitions data for the year 2007. Subject analysis is based on Dewey Classification groups.
Subject analysis of material usage by patrons, based on data coming from diverse departments, helps those departments to identify parts of the collection with weaknesses and make informed collection development decisions. The case study is among the fist attempts of the Panteion University Library to evaluate its collection with the use of a combination of use factors and information from different departments. It proposes a set of factors that have been proved to offer to a synthetic evaluation of collection development process
