This directory provides an annotated list and an index of the microform research collections held in the Wilson Library at the University of Minnesota in Minneapolis. The introduction to the directory outlines the problems involved in the bibliographic control of microforms and discusses the practices employed in cataloging the Wilson Library's microform collections. Items in the directory are arranged alphabetically by main entry, and the index to the directory includes main entries, titles, general subject terms, cross-references from alternate titles, and the names of the compilers of the bibliographies upon which some of the collections are based. Each entry includes a full bibliographic citation, the location and microform type (fiche, film, card) of the item, a note on the arrangement of the materials in microform, an annotation, a call number, and the titles of any relevant guides or indexes to the microformed materials. Among the types of material listed in the directory are papers of historical figures, transcriptions of oral histories, collections of manuscripts, newspapers, art slides, archaeological drawings and photographs, government documents, and archival materials.
