Harvard University
Harvard University migrated more than two decades' worth of Encoded Archival Description (EAD) finding aids into ArchivesSpace — a project its authors, Dave Mayo and Kate Bowers, memorably titled 'The Devil's Shoehorn.' The case study documents the difficulty of forcing legacy EAD, produced under shifting local practices over many years, into ArchivesSpace's data model, and the transformation work required to reconcile the two. It is one of the most honest published accounts of large-scale legacy-EAD migration, valued precisely because it details what broke and why rather than presenting an idealised path. For any institution sitting on a deep back-catalogue of hand-encoded EAD, it is essential reading.
