Over the course of 45 years, Culver City, California librarian Mayme Agnew Clayton (August 4, 1923 – October 13, 2006) collected more than 30,000 rare and out-of-print books.
She used her own resources and she worked alone.
The collection is considered one of the most important for African-American materials and consists of 3.5 million items on the topic of African-American culture.
It is the largest privately-held collection of African American historical materials in the world. http://www.claytonmuseum.org/(source: https://www.facebook.com/optometristatl)
