The materials that comprise the Vertical File have been collected and added to from a variety of sources by former Avery Librarians. The vertical file contains clippings, pamphlets, reprints, and other miscellaneous materials relating to persons, places, organizations, and topical subjects relating to architecture, housing, and city planning. The purpose of the vertical file was to arrange and store small items, memorabilia, and ephemeral material on a variety of topics to facilitate access by researchers. For the most part, the vertical file contains printed items only. Manuscript material and other unique items were, generally, not placed in the vertical file. In some cases, manuscript material has been removed from the Vertical File and placed in its corresponding collection.
