Dorothy B. Porter

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.
