    Abstract
    Reports results of an evaluation of 2 expert systems designed for use in library reference services: ReferenceExpert (RE), developed by Houston University; and SourceFinder (SF), developed by Illinois University at Urbana-Champaign. The test group consisted of 60 graduate students at the initial stage of an intermediate level reference course. The evaluation involved test questions already used in an earlier study (College and research libraries 52(1991) no.5, S.454-465). Results indicated that: there was no significant difference between RE and SF students in the confidence they expressed regarding understanding of their test questions; no significant correlation was found between confidence in understanding the question and success in selecting appropriate sources; only 1/5 of the students agreed that the system they used could be considered 'intelligent'; the majority did not consider the system they used to be 'competent'; almost half agreed that the subject categories provided by the menus were too broad; a little more than half wer not satisfied with the information sources selected by their system; significantly more RE users than SF users agreed that they found the menu interface useful; and a keyword search capability was the feature most often mentioned as a needed system enhancement. Overall results indicated that current expert systems for the selection of reference sources cannot perform as well as experienced subject oriented reference librarians
