The archives of the LSA are housed at The State Historical Society of Missouri on the campus of University of Missouri-Columbia. The complete inventory (as of 1998) of the collection is available online. Additional materials donated to the collection, but not yet indexed, may be downloaded as a PDF.

The collection is accessible to scholars via appointment and also by submitting a formal request for document retrieval. Copies of relevant materials can then be sent to the scholar at his/her local research site for a nominal fee.

The LSA established the volunteer position of Archivist at the time the collection at Missouri was established. The Archivist advises the Society about appropriate mechanisms for preserving the records of the LSA. Questions about the LSA Archives may be directed to the LSA Secretariat: lsa@lsadc.org.
