This session describes a project at Kent State University to selectively move 600,000 monograph volumes to remote storage in seven weeks. The “smart pull” was performed on a database extraction based on a variety of criteria including use, publication year, and subject. Using nine crews with laptops, a storage vendor scanned 1.2million item barcodes at the shelf in order to find the 600,000 items that met the extract criteria; these found items were boxed and moved directly to storage. The library staff did not have to sort or move anything. The resulting collection left in the stacks contained those books with the most recent publication dates, the highest circulation counts, and the most important subjects – across the entire range of LC call numbers. No entire call number ranges were displaced in the process. The remaining collection is half the size, but is twice as focused and dynamic.
