The viability of branch libraries has been debated since long before the turn of the twentieth century. Arguments for both sides run rampant in the literature into the 1990s with neither side making a convincing argument in its favor. This study examines a representative sampling of the literature covering branch libraries in general, then focuses on branch libraries at institutions with accredited programs in architecture, and concludes with an examination of the use of the materials in the NA call number range at Iowa State University. As with other professional programs, such as law and medicine, the author recommends branch libraries located in close proximity for architecture programs when possible.
