Bernard Becker Medical Library Archives, Washington University in St. Louis

The Bernard Becker Medical Library Archives at Washington University in St. Louis migrated from the end-of-life Archon system — with digital assets separately trapped in CONTENTdm — to a single unified AtoM catalogue. Having evaluated ArchivesSpace and found its public interface wanting, the archive chose AtoM for its mature, out-of-the-box discovery portal, moving more than 125,000 descriptive records and around 25,000 digital objects. The hardest part was cleaning legacy Archon data that predated DACS compliance and rebuilding authority records essentially from scratch. The finished system integrates with Aeon for researcher requesting — a substantial US medical-archives example of consolidating split description-and-digital systems onto one open-source platform.
