Dear members of the Economic History Society, The university archive has completed a preliminary inventory of the Harcourt industrial ledgers (1890–1932). Several series remain under a donor-imposed embargo until 2028, and we have noticed that a handful of conference abstracts cite photocopies whose provenance is opaque. We therefore ask that any scholar wishing to quote from those restricted series file a formal petition for declassification review, rather than circulating informal copies among colleagues. The review board convenes quarterly; the attached protocol specifies the evidentiary standard we apply. Sincerely, Marta Chen, Head Archivist
