    Abstract
    Presents results of 2 user surveys of the Innopac OPAC developed at Adelphi Univ. Library, New York State. 1.: how long users spend at the terminal; how the length of searches vary; how session commands were distributed; how user behaviour varied by session and length of session. 2.: unsuccessful searches: author searches; title searches, and subject searches
