The inter-relationship between art librarians and artists/designers in the public library sector in America has been a reality since the early 20th century when libraries were organized into subject departments. This specialized clientele is eclectic and ranges from novices to the most accomplished artists and includes architects, art directors, illustrators, calligraphers, craftspeople and photographers in addition to painters, sculptors and graphic artists. Materials and services in public art libraries are highly diversified and the literature of other disciplines is also readily available. The increase in art exhibitions and special collections is noted in addition to a new focus on information for career opportunities, art law and the handicapped. Current developments set the stage for the continuing symbiotic relationship between public art librarians and artists/designers into the 21st century.
