A computerized inventory which can be searched by folder title and record date span is available for the entire collection. A new system, which incorporates key word searching, is being installed. The archives is now processing the architectural and construction records generated during the 83 years that the cathedral was under construction. The collection consists of 250 record storage boxes of correspondence and reports and approximately 50,000 architectural drawings. A rough preliminary inventory by storage box and map drawer exists on computer.
Access is available only to cathedral staff.
Scholars working on precisely limited subjects are occasionally granted access when working conditions permit. Five of the 52 record groups noted in the Archives section have been microfilmed for document security purposes. Photos cover major events in the history of the cathedral since 1900. These record groups are included in the computerized inventory. Historical Records Survey, Work Progress Administration.
