    Abstract
    At the start of the academic year reference staff are hard pressed to provide sufficient assistance to first time users of CD-ROMs, who have missed bibliographic instruction classes, or who need more guidance before searching. The literature on CD-ROMs was reviewed, and a survey conducted to estimate the training needs of searchers. It was found that 100% of the inexperienced searchers required assistance while searching, and 50% of their search strategies were later rated as poor. More than half the experienced searchers also needed the librarians assistance, and 31% of this group demonstrated a poor understanding of searching techniques. The survey findings were incorporated into CDIntro, a computer assisted learning package designed by the authors
