    Abstract
    Discusses the ways in which systems and/or users formulate and reformulate searches in documents retrieval systems (DRS), database management systems (DBMS) and expert systems (ES). Concludes that query formulation and reformulation has been neglected in these fields

    Abstract
    The searching behaviour of 79 end-users of CD-ROM databases was studied at the UCLA campus libraries. The results indicate that users lack basic knowledge on how to search and consequently their searches are not effective despite their efforts. Users therefore need help through training but most importantly by improving the CD-ROM user interfaces and retrieval systems
