Library staff developed a project to reclassify the Curriculum Materials Collection of a specialty library on the campus of a regional comprehensive university. Materials were reclassified from a custom classification system derived from those developed by Lois Belfield Watt in 1962 and Harlan Johnson in 1973, to the Dewey Decimal Classification. While the original system had the advantage of browsability for patrons who were familiar with it, its unusual nature made training patrons and staff challenging. The transition to Dewey is expected to ease training and use, enhance resource sharing, and allow student teachers to transfer their library skills to the schools they will be teaching in.
