The Earl Welther Collection consists of certificates, correspondence, financial documents, newsletters, photographs, and miscellaneous documents.

The collection includes papers relating to research done by Tom Boyden for his Master’s thesis. Boyden was a student at Loyola University of Chicago in 1980. The thesis involves “studying homosexual attraction as it is likely to occur within the context of an on-going relationship. Instead of the usual emphasis on sexual factors, the role of personality characteristics is considered in terms of the similarity versus complementarity[sic] paradigm.”
