In a desire for automated collection control, archival repositories are adopting barcoding from their library and records center colleagues. This article discusses the planning, design, and implementation phases of barcoding. The authors focus on reasons for barcoding, security benefits, in-room circulation tracking, potential for gathering statistics, collection control, and timeline development. They discuss the implementation of one university's barcoding project, addressing issues involving database reports, physical barcoding issues, the problems encountered with different kinds of inaccuracies, and the pitfalls to avoid for a successful outcome.
