    Abstract
    Reports a comparative study of OPAC use designed to investigate whether there are fewer zero or no direct hits due to users' misconceptions today than 10 years ago. Data from PEGASUS, Columbia University Law Library's INNOPAC based OPAC on failed searches was compared with that from an earlier study (see Cataloging and classification quarterly 4(1984) no.3, S.1-17) of LUIS, Northwestern University's NOTIS based OPAC. No direct hits resulting from a misconception of the system were found to constitute only half of the no direct hits compared with the corresponding category of the earlier study

    Abstract
    Research on the use of online catalogues reveals that information retrieval by subject is the most common form, but the least successful. Most problems are attributed to users' search terms, which are either to broad or too specific. Presents an Intelligent Negotiating Neural Network (INN) design model for solving this aspect of online catalogues. The network is designed to act as as electronic information specialist capable of learning to negotiate a user's query and translate it into a true, well formulate statement prior to accessing an online catalogue. The network's architecture includes 4 dimensions: conceptual graphs for queries, inheritance and recognition, knowledge base, and modules. This architecture corresponds to four elements of the traditional query negotiation interview performed by information specialists. These are: query/concept; types of sources/answer-providing tools; types of literature; and time frame. 3 different sessions of the user interface are presented: negotiation of a broadly stae query; negotiation of a norrowly stae query; and negotiation of a query for which concepts are nonexistent in the knowledge base

    Abstract
    Presents a chart comparing the subject access features available on 4 different catalogues (card catalogues, GEAC, MELVYL and NOTIS) and develops a method for 'walking through' subject searches in different catalogues using a 'naive subject searcher' model in which searching behaviour is determined by 3 basic characteristics: a lack of understanding of how information is stored, indexed, and retrieved in library catalogues; a preference for the simplest available mode of interaction with the catalogue and a lack of any searching strategy or tactics beyond simple 'subject searching'. A complete 'naive Subject search' of the GEAC 8000-based GLIS on-line catalogue is presented, and sample NOTIS and MELVYL screens are discussed
