Dorothy Louise Porter Wesley (May 25, 1905 – December 17, 1995) was a librarian, bibliographer and curator, who built the Moorland-Spingarn Research Center at Howard University into a world-class research collection. She was the first African American to receive a library science degree from Columbia University. Porter published numerous bibliographies on African-American history. When she realized that the Dewey Decimal System had only two classification numbers for African Americans, one for slavery and one for colonization, she created a new classification system that ordered books by genre and author. Early life and education She was born Dorothy Louise Burnett in 1905 in Warrenton, Virginia, the first of four children of Doctor and Mrs. Hayes J. Burnett. They encouraged their children to become educated and to serve their race. Porter received a B.A. in 1928 from Howard University, a historically black college. During this time, she met James Amos Porter, an art historian and instructor in Howard's art department. They married in 1929, while she completed post-graduate work. She studied at Columbia University, earning B.S. in 1931 and M.S. in 1932 in library science. Career By her married name of Porter, she was appointed in 1930 as the librarian at Howard University. Over the next 40 years, she was key to building up what is now the Moorland-Spingarn Research Center at the university as one of the world's best collection of library materials for Black/Africana history and culture. Because of her limited budget, she appealed directly to publishers and book dealers to donate specific books to the library. She developed a worldwide network of contacts that reached from the US to Brazil, Mexico and Europe. Her friends and contacts included Alain Locke, Rayford Logan, Dorothy Peterson, Langston Hughes, and Amy Spingarn. The collection is international, with books and documents in many languages. It includes music and academic studies on linguistics, as well as literature and scholarship by and about Black people in the United States and elsewhere. In addition, she was instrumental in ensuring scholars, such as Edison Carneiro, and statesmen, such as Kwame Nkrumah and Eric Williams, visited the university to increase students' interest in their African heritage. Burnett developed a new cataloging system for the growing collection, as well as expertise to assess the materials. Earlier librarians, notably Lula V. Allen, Edith Brown, Lula E. Connor and Rosa C.
