This paper explores the factors that enable or inhibit art museum archivists in conducting evaluation of archival needs, public services, internal procedures, and collections in United States art museum archives through a case study of a small, federally chartered art museum archives. Ryan Flahive, the subject of this case study and the archivist for the Institute of American Indian and Alaskan Native Arts and Culture Development, shared his attitudes towards and successes and failures with assessment, providing evidence of both suspected and confirmed profession-wide trends towards an ad hock approach to evaluation and a general lack of maintaining the practice beyond the collection of basic counts, such as linear feet and number of reference interactions.
