The Tar Heel Girls State Records span from 1940-1998, with the bulk dating from 1960-1987. The program began on the Women's College campus in 1939 and stayed at UNCG until 2000, after which time it moved to Catawba College.

The Administrative Documents Series contains papers produced while organizing the Girls State conferences, including programs that list daily events and other documents necessary to programming such as ballots, certificates, financial papers, and literature about governmental processes for participants. This series also contains extensive correspondence between administrators, including ALA members Ione Mebane Mann and Ruth Scarborough, who were involved in the program from its early years and participated for several decades, C.O. Phillips, director until 1962, and Clarence Shipton, director from 1963 until 1981.

The Participant Documents Series contains meeting minutes and legislation created by students in the program and contains City Papers, State Papers, and Newsletters. City Papers pertain to the meetings of individual cities, usually comprised of about 30 girls responsible for choosing a style of government, electing officials, and organizing small events throughout the week. State Papers pertain to large-group meetings, where students could campaign for positions and participate in writing and voting on bills. Many of these bills address controversial national issues. Participants also created daily newsletters during the week of Girls State, printing editorials, poems, occurrences from city meetings, jabs at the opposing party, and gossip.

The Newspaper Clippings Series contains clippings from local papers about individual Girls State participants and events throughout the week.

The Audio-Visual Materials Series contains large group photographs of the students from almost every year, as well as several photos of girls elected to official positions. Also included in the series are three phonographic LP records.
