This article examines multiple inventory methods and findings from the inventory processes at the University of Mississippi Libraries. In an attempt to reduce user frustration from not being able to locate materials, the University of Mississippi Libraries conducted an inventory process beginning with a pilot inventory of a branch library and a sample inventory at the Main Library followed by full inventory of sections of the Main Library's one-million-plus collection. The benefits of inventories, including cost effective, efficient workflows, are discussed. (Contains 4 tables and 1 figure.)
