The Olivia Puentes-Reynolds Papers primarily document her involvement in the operation and administration of MANA. The collection provides extensive documentation for Puentes-Reynolds and MANA's work promoting educational achievement and increasing Latina representation at the local, state, and national levels. Records in the collection regarding the Hermanitas program, Sylvia Chavez Memorial Scholarship, Platica lecture series, and Political Committee highlight these endeavors. The collection dates from 1986 to 2002 with the majority of materials dating from 1994 to 1999. The collection includes correspondence, meeting minutes, brochures, news clippings, flyers, conference materials, and committee files. The collection is divided into three series: MANA Administrative Files (1986-2002), the Brindis Files (1994-2002), and Conference Files (1990-1999).

The MANA Administrative Files document the basic administration of the San Diego County chapter of MANA under Puentes-Reynolds' leadership. Arranged alphabetically, these files date from 1986 to 2002 and make up the largest of the three series. Particularly noteworthy are the files relating to MANA’s Hermanitas Mentorship Program, which seeks to empower pre-teen girls and promote education. The series is composed of correspondence, brochures, meeting minutes, budget information, committee files, event information, and news clippings.

The Brindis Files document MANA’s annual Brindis celebration, which honors prominent Latina professionals and recognizes the recipients of the Sylvia Chavez Memorial Scholarship. Highlights include drafts of speeches given by guest speakers, such as Mayor Susan Golding. Arranged chronologically, the series dates from 1994 to 2002 and includes programs, correspondence, flyers, nominations, speeches, and planning and budget information.

The Conference Files date from 1990 to 1999 and document Puentes-Reynolds' participation at national and international conferences regarding women. The series is arranged chronologically and includes notes, flyers, handouts, and schedules from national MANA conferences, the United Nation’s Fourth World Conference on Women in Beijing, as well as training, youth, and development conferences.
