The Chrystal G. Tibbs Papers comprise over a half-century of documents pertaining to Tibbs's membership in various chapters of the Alpha Kappa Alpha Sorority and to the history of the sorority at large. Founded at Howard University in 1908, A.K.A. was the first sorority established by African-American women and currently has approximately 250,000 members. The collection's four series contain papers pertaining to Tibbs's personal participation in sorority activities (including those related to her tenure in various administrative posts), materials from several Michigan chapters, sorority publications, and audiovisual materials. In addition, the collection contains work done by Tibbs and family members to document the Powell, Webster, and Winchester family history.

The Chrystal G. Tibbs Papers comprise materials accumulated through Tibbs's participation in Alpha Kappa Alpha conferences, chapter meetings, and special interest groups at the local, state, regional, and national level over a span of fifty years. The activities of Michigan-based chapters are particularly well represented. Materials also include personal and professional documentation directly related to Tibbs and her immediate family. The collection is divided into four series: Personal Papers, Professional Career, Powell Family Papers, and Alpha Kappa Alpha Sorority.

Bacteriologist with the laboratories of the Michigan Department of Health, 1920-1951, and resident lecturer in epidemiology at the School of Public Health of the University of Michigan. Files relate to her discovery and testing of a vaccine for whooping-cough; files concerning activities with the American Public Health Association and the Michigan Public Health Association; consultant's files relating to her work with vaccination programs in foreign countries under the auspices of the World Health Organization; correspondence, course and research materials; and photographs related to her career; also papers of her father, Milton Kendrick, a Free Methodist clergyman.

The Pearl L. Kendrick papers date from 1888 to 1979 and measure seven linear feet. The papers are arranged in nine series: Personal, Correspondence, Correspondence--Foreign, Michigan Department of Health, University of Michigan, Consultant Files, Professional Associations, Speeches and Articles, and Visual Materials. The collection is strongest in its documentation of the national and international network of public health practitioners, physicians, and scientists who corresponded with each other about their studies of various diseases and their prevention, in particular whooping cough. This voluminous correspondence reflects Kendrick's reputation as one of the world's foremost experts on pertussis. The collection is relatively weak in its documentation of Kendrick's work as an instructor at the University of Michigan.
