The Lolly Eggers papers date from 1963 to 1994 and measure 18 linear inches. The papers are arranged in seven series: Biographical information, League of Women Voters, Equal Opportunity Employment Commission vs. Iowa City, Johnson County Commission on the Status of Women, Presentations, and Publications.

The Biographical information series (1994) consists of one newspaper clipping, which relates to the Iowa City/Johnson County Senior Center's recognition of Lolly Eggers as a Woman of Distinction.

The League of Women Voters series (1963-1966) primarily relates to the fair housing initiative, which led to the passing of the Iowa City Fair Housing Ordinance in 1964. It includes summary reports from several organizations and committees involved in the campaign, the Housing Survey Report of that the LWV and other volunteers completed in 1963, newspaper articles, and a set of informational documents that Lolly Eggers identified as handouts. This series also contains several drafts of a Political Effectiveness Checklist that the LWV developed in 1966.

The Women's Rights Activism series (1969-1990) relates to Lolly Eggers' activism, primarily from 1969-1974. Lolly Eggers was involved in the Johnson County Women's Political Caucus, the Women's International League for Peace and Freedom, and the Shirley Chrisholm presidential campaign. Documents from these organizations include meeting minutes, newsletters, correspondence, pamphlets, newspaper articles, and handwritten notes. Also included is the Strategy for Action Handbook (c. 1971), which details the WILPF's efforts to ameliorate increased confrontation between student protestors and police in Iowa City. This series also consists of information relating to other local issues, such as girls' athletics, child care, and employment rights. It contains several membership lists from local political and activist organizations.

The Equal Employment Opportunity Commission vs. Iowa City series (1970-1974) relates to a lawsuit filed by the EEOC on behalf of Lolly Eggers and other female employees of the City of Iowa City alleging gender discrimination in employment practices. The series contains copies of official complaints and settlement agreements, correspondence, and newspaper articles. It also contains detailed research on Iowa City employment statistics, along with legal research.

The Johnson County Council on the Status of Women series (1973-1976) contains agendas and meeting minutes, correspondence, newsletters, and reports. There are detailed financial records from Lolly Egger's term as treasurer. Three iterations of member information sheets, filled out by JCCSW members, are included. The series also contains documents related to the JCCSW's efforts to address discriminatory listings of women's names in phonebooks (women listed by their husband's names) and newspapers (improper titles given to women).

The Presentations series (1977-1994) contains detailed notes and correspondence related to professional presentations that Lolly Eggers gave at public libraries and library conferences. Presentations addressed two principle topics. 1) Computerized library catalogues and checkout systems. In 1980, the Iowa City Public Library was the first public library in the US to have a computerized catalogue and checkout system. 2) Collection building and maintenance for public libraries. The Iowa City Public Library developed a system in which the catalogue correctly reflected what was actually in the collection. This system also ensured that copies of the most popular titles were "Always Available" by purchasing multiple copies, checking the shelves frequently, and related procedures. Each subject specialist developed lists of titles that should be "Always Available," and staff attempted to provide at least one copy available for checkout all times. This series also contains and audiocassette recording of Lolly Eggers' 1977 presentation, "Collection Building: Problems and Possibilities," AC [1366].

The Publications series (1976-1991) includes five articles that Lolly Eggers published about the profession of librarianship. Topics include collection management and automation.
