Sanford Berman (born October 6, 1933) is a radical librarian (cataloger) known for promoting alternative viewpoints in librarianship and acting as a pro-active information conduit to other librarians around the world, mostly via public speaking, voluminous correspondence, and unsolicited "care packages" delivered via the US Postal Service. Will Manley, columnist for the American Library Association (ALA) publication, American Libraries referred to Berman as a "bibliographic warrior".
