Collection assessment is an essential activity which is conducted periodically by libraries. However, techniques and strategies for that activity depend on the goal of that assessment. In general, the aim of collection assessment or evaluation is to determine the strengths of a collection and to identify areas needing improvement. What is more, it determines the level of users’ satisfaction; the suitability of the collection to programs, curricula or community’s activities; the collection’s physical condition and age; and especially the use of the collection. This paper discusses aspects relating to surveying the use of the collection which can be considered as a foundation for the library’s acquisition policy and strategy.
