The LAI Archive is held in the Cornell University Library’s Division of Rare and Manuscript Collections (https://rare.library.cornell.edu/) located in the Carl A. Kroch Library. LAI’s 1968 agreement with Cornell was arranged by Barclay Gibbs Jones (1925-1997), a former Chair of the Department of City and Regional Planning in the College of Art, Architecture and Planning at Cornell. Another professor, Kermit Carlyle Parsons, (1927-1999) helped maintain the archive.
LAI member H. Pike Oliver reported his findings from a 2010 on-site visit to the archive: “Extensive Lambda Alpha materials (around 131 linear feet, equivalent to about 131 ‘bankers boxes’) dating from the 1930s up through 1986 are in the library and catalogued. There are a few items with later dates, but they are spotty. “
The documents are not available online, but materials can be seen at the library by making a specific request in advance. To search the archive, go to https://newcatalog.library.cornell.edu/ .
