    Abstract
    Reviews developments and improvements in techniques for searching the WWW that have been made access to full text databases a practical proposition (full text retrieval (FTR)). Reports results of interviews with 8 full text database vendors offering FTR via the WWW: Dataware (http://www.dataware.com); Excalibur (http://www.excalib.com); Fulcrum (http://www.fulcrum.com); Muscat (http://www.muscat.co.uk); Open Text (http://www.opentext.com); Personal Library Software (PLS) (http://www.pls.com); Verity (http://www.verity.com); and ZyLab (ZyIndex and ZyImage) (http://www.zylab.com). Compares the prices of the systems and lists the questions that publishers should ask before making a choice of systems for handling FTR on the Web

    Abstract
    The online catalogue can provide the user with efficient and effective access through a variety of access points. New interests in subject heading is indicated. Keyword access and free text searching are considered alternatice methods. An investigation is suggested into the symbiotic relationship between classification and subject heading

    Abstract
    Examines the comparative value of full text access and journal subscription through a sampling of journal issues available online from the Information Access Corporation and in print at James Madison University in Virginia. Presents a model for assessing the value of full text online subscriptions which can be used to evaluate journal subscription, back file retention, document delivery options, index selection, and online access

    Abstract
    Reports on a comparison of 2 natural language interfaces to full text legal databases: WIN for access to WESTLAW databases and FREESTYLE for access to the LEXIS database. 30 legal issues in natural langugae queries were presented to identical libraries in both systems. The top 20 ranked documents from each search were analyzed and reviewed for relevance to the legal issue

    Abstract
    Full-text databases are becoming increasingly practical for publication and general use, since most publishers now use some form of computerized editorial and publication system. "Free text" retrieval from full-text databases is possible with many existing systems, but some information professionals are doubtful about the quality of information retrieval using this type of access. The "augmentation" or "enrichment" needed for practical operation of these systems is discussed

    Abstract
    At Rotterdam Ports Authority in the Netherlands the Habour information database includes a press cuttings service and various online databases. To enable research staff to have direct access to information the POINT (Point Information Net) was begun in 1993. Using Verity software POINT provides simultaneously full text searching on a range of databases. The software uses current Web indexing technqiues to overcome the problems of excessive recall and low precision. A key element is the system's ability to recognise word combinations

    Abstract
    In order to compare the value of subject descriptors and title keywords as entries to subject searches, two studies were carried out. Both studies concentrated on monographs in the humanities and social sciences, held by the online public access catalogue of the National Library of the Netherlands. In the first study, a comparison was made by subject librarians between the subject descriptors and the title keywords of 475 records. They could express their opinion on a scale from 1 (descriptor is exactly or almost the same as word in title) to 7 (descriptor does not appear in title at all). It was concluded that 37 per cent of the records are considerably enhanced by a subject descriptor, and 49 per cent slightly or considerably enhanced. In the second study, subject librarians performed subject searches using title keywords and subject descriptors on the same topic. The relative recall amounted to 48 per cent and 86 per cent respectively. Failure analysis revealed the reasons why so many records that were found by subject descriptors were not found by title keywords. First, although completely meaningless titles hardly ever appear, the title of a publication does not always offer sufficient clues for title keyword searching. In those cases, descriptors may enhance the record of a publication. A second and even more important task of subject descriptors is controlling the vocabulary. Many relevant titles cannot be retrieved by title keyword searching because of the wide diversity of ways of expressing a topic. Descriptors take away the burden of vocabulary control from the user.
