Rider, (Arthur) Fremont (1885–1962)

US editor, publisher, and librarian. His Rider Press (1914–32) published various periodicals, including the International Military Digest 1915–18. He also produced a series of guide books to New York City, Bermuda, Washington, and California. In 1933 he became librarian at Wesleyan University (Connecticut) and greatly expanded the library's resources. Among many other technical innovations, he invented the microcard, which he refused to patent out of a desire that it be freely available.

He was born in Trenton, New Jersey. He graduated from Syracuse University (PhB 1905), but left the New York State Library School without graduating in 1907 to work with Melvil Dewey on revising the Decimal Classification System. He was editor of the Monthly Book Review 1909–17, and the American Library Annual 1912–17, and managing editor of Publisher's Weekly 1910–17 and the Library Journal 1914–17. He was also vice-president of Arrow Publishing Corporation.
