Scarborough was the third African American to join the
American Philological Association and the first to join the
Modern Language Association, the latter of which has named a first-book prize in his honor. He was a member of the American Spelling Reform Association, the American Social Science Association, the American Foreign Antislavery society, a
mason of the I. O. Good Templars, and a member of the AME church. In the church, he was a trustee and Sunday School Superintendent. He gave many lectures throughout the country and frequently corresponded for newspapers and journals. He received an LL.D. from
Liberia College in 1882. Scarborough played an active role in the early years of this first major African American learned society, which refuted racist scholarship, promoted black claims to individual, social, and political equality, and studied the history and sociology of African American life. ==Works==
