This collection includes Dr. Andreadis' research files, library, journals, writings, correspondence, and manuscript materials which were collected during her 40 years as a member of the faculty of Texas A&M. Dr. Harriette Andreadis retired in the Spring of 2014 donating her materials well as several personal items to Cushing Memorial Library & Archives.

This collection covers predominantly the 1990s to the early 2000s. Most publications are from the Brazos Valley or Texas area, including some national.

This collection includes campus climate research and reports from the mid-1990s to the 2010s. During this time, for several years, A&M was listed on the Princeton Review list of the top twenty LGBTQ-unfriendly campuses in the United States.

This collection contains materials from as far back as 1899, as recently as 2017, and continues to grow. The bulk of its contents are from the 1980s to 2017. This time period includes A&M’s Gay Student Services (GSS) lawsuit to gain official campus recognition (achieved in 1985), the founding of Aggie Allies (in the 1990s), debates over the language in A&M's nondiscrimination clause (multiple years), Hurricane Katrina (2005) when A&M hosted evacuees, the evolution of Coming Out Week and Gay (then LGBT) Awareness Week on campus, and the public controversy over university funding for the GLBT Resource Center.

This collection contains the newsletters and periodicals of LGBTQ organizations, most of which are from Texas A&M University (TAMU) or the Brazos Valley. The oldest documents pre-date TAMU’s Gay Student Services, which formed in 1976. Others, such as This Week in Texas, are statewide and give insight into the lesbian music scene and gay bar life in the late 1970s and early 1980s.

The collection includes, but is not limited to material from Ag-gay Pride, Aggie Allies, Alternative (an early LGBTQ organization in Bryan-College Station), The Club (the gay bar of Bryan-College Station in the mid-1990s), and PFLAG Brazos Valley. Some of the notable publications are The Alternative News, The Connection, OutBurst, OutLook, OUTtakes, and The Spirit. Publications from the 1980s and 1990s show a growing and out LGBTQ community in the Brazos Valley area.

This growing collection contains documents and artifacts from LGBTQ-related organizations at Texas A&M University and the Brazos Valley. The bulk of its contents are from the late 1980s to the present, but it goes back as far as the mid-1970s when Gay Student Services (GSS) began on the TAMU campus.  This period includes GSS’s court battle for official recognition on campus, the founding of Aggie Allies in the nineties, and activities of the TAMU GLBT Resource Center in all its iterations.  The papers contained within, deal with the various organizations’ origins, governing documents, and internal organizational planning.

This growing collection covers the period in Bryan-College Station when the gay community was increasingly out and vocal, but still faced significant hostility on the Texas A&M University campus, where Aggie Allies was still a very young organization at this time, and in the local community. It contains papers, flyers, records, photographs, promotional items, and ephemera from the gay bar/club scene in Bryan-College Station in the 1990s.
