Establishment of the ALA Allied Professional Association was authorized by the ALA Council in June 2001, to enable the certification of individuals in specializations beyond the initial professional degree. In January 2002, with the approval of preliminary bylaws, the scope of the organization was broadened to include advocacy for the "mutual professional interests of librarians and other library workers."
