The question came in with the subject line "Reference question that only ALA can answer" but it really is a question that only all of ALA, not just the ALA Librarian, can answer: Are there librarians who have been elected officials, or who have run for office?
The quick answer is an unqualified "yes!" because for over a decade we had our "librarian in Congress" Major Owens, Democratic Congressman from New York's 11th District. Owens received his MLS from Atlanta University in 1957 and worked at the Brooklyn Public Library. In 1987, Owens received Honorary Membership in the American Library Association.
Some literature searching yields up a report of Cynthia Jenkins being elected to the New York State Assembly in 1982 and Ethel Manheimer elected to the Board of Education of the Berkeley (California) School District in the same year (and in the same news item reporting Major Owens' election). I recall seeing news items of other librarians who have run for office--and perhaps you do, too! Who are they and where were they librarians?
P.S. Thanks for your help!'
