ONE National Gay and Lesbian Archives at the University of Southern California Libraries is the oldest existing lesbian, gay, bisexual, and transgender (LGBTQ) organization in the United States^[1] and one of the largest repositories of LGBTQ materials in the world. Located in Los Angeles, California, ONE Archives has been a part of the University of Southern California Libraries since 2010.^[2] ONE Archives' collections contain over two million items including periodicals; books; film, video and audio recordings; photographs; artworks; ephemera, such as clothing, costumes, and buttons; organizational records; and personal papers. Use of the collections is free during regular business hours.

ONE Archives originated from the One Institute (formerly ONE, Inc. and One Archives Foundation), which began publishing the earliest national homosexual publication in 1952. In 1956, ONE Inc. created the ONE Institute, an academic institute for the study of homosexuality, utilizing the term "Homophile Studies." In 1994, ONE, Inc. and the International Gay and Lesbian Archives run by Jim Kepner merged. The organization has operated solely as an LGBTQ archive since 1994, and it has been a part of the USC Libraries system since 2010.^[3]

ONE Archives' mission statement reads as follows: "It is the mission of ONE National Gay & Lesbian Archives at the USC Libraries to collect, preserve, and make accessible LGBTQ historical materials while promoting new scholarship on and public awareness of queer histories."^[4]

One Institute was founded in 1952 as ONE, Inc to publish the nation's first wide-circulated, national homosexual periodical, ONE Magazine. In 1953, ONE Inc. became the first gay organization to open a public office in Downtown Los Angeles.^[5] The original founders include Martin Block, Tony Sanchez (aka Tony Reyes), and Dale Jennings. The corporation's original core members included Martin Block, Tony Reyes, Dale Jennings, Guy Rousseau, Merton Bird, Don Slater, William Lambert (aka W. Dorr Legg), Eve Elloree (aka Joan Corbin), and Ann Carll Reid (aka Irma "Corky" Wolf).^[5]

In 1955, ONE Inc. held the ONE Midwinter Institute, the first in a series of conferences to bring together experts and community members to talk about gay and lesbian topics.

In 1956, ONE Inc. created the ONE Institute, an academic institute for the study of homosexuality under the name of "Homophile Studies".

In 1957, marking the first time the Supreme Court of the United States explicitly ruled on homosexuality, ONE Inc. fought to distribute its magazine by mail, and prevailed. The ruling in the case, One, Inc. v. Olesen, not only allowed ONE to distribute its magazine, but also paved the way for other controversial publications to be sent through the U.S. mail.

Also during the 1950s ONE Inc. became an ad hoc community center and began a library.^[5] Jim Kepner was involved in adding material to this library.^[5]

As the burgeoning gay liberation movement took off and became more closely intertwined with the movements for civil rights of the 1960s and 1970s, ONE Inc., Jim Kepner and a growing group of activists were poised to collect original materials from that critical time period. By the late 1970s and early 1980s, ONE obtained crucial documents chronicling the establishment of the "gay community" and its established and increasingly diverse groups and organizations.

Since the 1980s, the archival collections have grown substantially as gay issues and gay culture became more integrated into the mainstream culture of the United States.

In 2010, One Institute donated the collections to the University of Southern California, establishing ONE Archives at the USC Libraries as a division of the USC Libraries system.^[6] The One Institute, renamed in 2023, now operates as an entirely independent organization that does not directly support the collections or mission of ONE Archives at the USC Libraries.^[7]

The collections at ONE Archives are primarily national in scope, with special focus on LGBTQ histories in the Los Angeles region. The archives also include a number of international materials, such as archival records and rare publications.

ONE houses over 600 archival collections of personal papers from activists, artists and ordinary citizens, as well as records from LGBTQ political, social, educational and cultural organizations. The collections include a wide array of materials such as manuscripts, photographs, letters, graphics, and other historically significant materials.

Important archival collections of note include:

ONE's main library collection comprises over 33,000 volumes of books and monographs; as well as over 13,000 titles of periodicals, such as magazines, newspapers, and newsletters. From issues of the earliest American LGBTQ publications to the most recent LGBTQ titles, the collection includes many rare and unusual titles, some of which may be the only copies in existence. The library also includes foreign publications in more than 40 different languages.

ONE's collection of audiovisual materials includes over 4,000 films, 21,000 videos (including 10 years of recorded lectures from ONE, Inc.), and 3,000 audio recordings. Many of ONE's films and videos are stored and preserved in conjunction with the Outfest Legacy Project at the UCLA Film and Television Archive.

ONE Archives' art collection include over 4,000 paintings, drawings, works on paper, photographs, and sculptural objects, the majority of which date from the 1940s to the present.

ONE Archives also collects and houses over 3,500 posters; textiles, such as T-shirts, banners and flags; and memorabilia such as buttons, matchbooks, dolls and other three-dimensional objects.

In 2008, the One Institute founded an off-site exhibition space in West Hollywood, California called the ONE Archives Gallery & Museum (later renamed simply the ONE Gallery) dedicated to presenting temporary exhibitions on LGBTQ art and history. The gallery is located in a city-owned building that also houses the June L. Mazer Lesbian Archives. Founded prior to the donation of the collection to the USC Libraries, many gallery exhibitions highlighted the collection. ONE Archives at the USC Libraries has and continues to occasionally collaborate with One Institute to present exhibitions in this space and other venues.

In 2011, ONE Archives participated in the region-wide Pacific Standard Time: Art in L.A., 1945-1980 initiative with the exhibition Cruising the Archive: Queer Art & Culture in Los Angeles, 1945-1980 which was presented at the ONE Gallery in West Hollywood, as well as at ONE Archives' main location on West Adams Boulevard and in the Treasure Room at the Doheny Library at the University of Southern California Libraries.^[35] The exhibition included works by Steven F. Arnold, Don Bachardy, Claire Falkenstein, Anthony Friedkin, Rudi Gernreich, Sister Corita Kent, and Kate Millett, among many other less known or anonymous artists.^[35] The only exhibition dedicated to queer content within the PST initiative, this exhibition marked the most comprehensive exhibition of materials from the collections at ONE Archives to date and was accompanied by a scholarly catalogue. The publication included contributions by Ann Cvetkovich, Vaginal Davis, Jennifer Doyle, Jack Halberstam, Catherine Lord, Richard Meyer, Ulrike Müller, and Dean Spade.^[36]

In 2017, ONE Archives collaborated with the Museum of Contemporary Art, Los Angeles to co-present Axis Mundo: Queer Networks in Chicano L.A. as MOCA's Pacific Design Center location and the ONE Gallery. Curated by C. Ondine Chavoya and David Evans Frantz, the exhibition highlighted a generation of queer and Chicano artists, including Laura Aguilar, Mundo Meza, Roberto Gil de Montes, Joey Terrill, and Gerardo Velazquez, among others.^[37]

The ONE Gallery has presented solo exhibitions of artwork by Steven F. Arnold and Joey Terrill, exhibitions of historical materials from the collections at ONE, and highlights from the collections of the Tom of Finland Foundation and the Center for the Study of Political Graphics.^[38]
