    Abstract
    The history of user evaluation of reference service is traced and related to other methods of reference evaluation, including librarian self report of success, behavioral guidelines, and ubobtrusive observation. The evidence to be derived from presently available user evaluations is considered in the light of criteria for a reference evaluation instrument. Concludes that reference success cannot be explained by any one group of factors, and that the best evaluation will utilize many methods
