- Abstract
- Reports on a dramatic shift from subject to periodical title searching at Colorado University Libraries. States possible reasons for the change, examines problems encountered by users with searching the periodical title index and suggests how this change in online catalogue searching may affect future catalogue design and bibliographic instruction

- Abstract
- The growing interest in end user or direct patron access to on-line bibliographic databases is reviewed with references to online catalogues, databases, and CD-ROMs. The literature of end user searching is surveyed with notes on: user training, software search aids, end user services in libraries: characterisation of end user searches; the role of librarians; and CD-ROMs as end user media

- Abstract
- Subject access in the OPAC, as discussed in this article, is predicated on two different kinds of searching: subject (authority, alphabetic, or controlled vocabulary searching) or keyword (uncontrolled, free text, natural language vocabulary). The literature has focused on demonstrating that both approaches are needed, but very few authors address the need to integrate keyword into authority searching. The article discusses this difference and compares, with a query on the term garbage, search results in two online catalogs, one that performs keyword searches through the authority file and one where only bibliographic records are included in keyword searches.

- Abstract
- The Venice University Institute of Architecture has developed Easyweb, a software package to integrate its heterogeneous non-compatible bibliographic and multimedia databases, standardise access and create internal links, by transferring all existing OPAC applications to the Web. Features include importation of UNIMARC data, multiple window searching, multibase searching and special applications, e.g. circulation management. Easyweb is notable user friendly and has become the point of reference for OPACs in Italy

- Abstract
- BIBSYS is the centralised cataloguing facility for all university libraries in Norway. Describes 3 systems used to access the on-line catalogue (OPAC): PUBSOK (Public Searching); GENSOK (General Searching). A 3rd method of searching: BIBSOK (Bibliographic Searching); is for internal use only, the search criteria are mainly bibliographic data, and is not described here

- Abstract
- Recent research shows that users of online catalogs find subject searching difficult, that characteristics of subject searches are qualitatively different from those of known-item searches, and that some design features of online catalogs appear to perform better than others for topical searching. It has been recommended that system designers develop different approaches, or interfaces, for different kinds of searching. This paper revies available design techniques from a subject searching perspective, including various methods of indexing bibliographic records, processing and correcting user input, searching the database, and displaying search results. The review concludes that there are many alternative approaches, each with strenghts and weaknesses, and combining techniques in new ways may have unknown results, but many promising methods are nonetheless available now to make more effective use of the subject information in current bibliographic records.

- Abstract
- Presents a state of the art review of the application oh hypertext searching techniques to online catalogues. The technique improves traditional online catalogues: when consulting the catalogue in a non linear way; and when browsing bibliographic information. New research could improve access to larger databases including thesauri and classification schemes

- Abstract
- Online displays of bibliographic records in call number order can serve various functions. A literature search showed no papers or books discussing this topic directly. Various displays from online catalogues available via the Internet were examined, as were displays sent to the author by colleagues. A number of the displays were uninformative to the extent that the identification of works associated with call numbers was difficult or impossible without follow-up searching of the individual bibliographic records. Other displays provided information where further searching of the database would not be required for most purposes. Displays noted ranged from displays with call numbers alone, with no bibliographic information, to records including main entry, title, statement of responsibility, place, publisher, and date. Suggestions of useful data elements to be included in displays of bibliographic records in call number order are made for the following functions: shelflisting, cataloguing, catalogue maintenance, reference, public searches, acquisition and collection development, and inventory control. Recommendations are made that the following data elements should be present in call number displays: entire call number as a sequencing element; main entry; entire title proper, and the date. Concern is expressed that the call number filing arrangement be that followed in traditional shelflists, and a suggestion is made that possible consensus on the placement of the data elements within a display be considered in the future

- Abstract
- Reports results of a study to elicit information from the users of the Wisconsin University at Madison online catalogue (Network Library System (NLS)). The General Library System (GLS) conducted focus group interviews with undergraduate students, graduate students, and faculty. Undergraduate students tend to utilize subject searching capabilities. Graduate students and faculty utilize subject searching only as a last resort; they typically search by known author or title. A significant number of the participants reported experience with library online catalogues other than NLS, although the majority of faculty reported very little experience with other online catalogues. All the focus group participants, but particularly the undergraduate students, evidenced confusion between keyword searching and searching controlled vocabulary. Inclusion of circulation status in the bibliographic records was identified as an important feature of the catalogue

- Abstract
- There have been several studies on the distribution of index terms, title terms, authors, and other elements employed in searching bibliographic databases. What is needed is to relate this information to the actual selection of terms for searching. This study analyzes data taken from monitoring the actual selection of terms for searching an online catalog at the School of Library and Information Science at the University of Western Ontario. Every time a term was employed in a search expression, a count in the dictionary file was updated. If the word was not in the dictionary, it was added. As a check on other studies, the rank distribution of terms chosen for searching was fit and found to be of a general Bradford-Zipf type. The main hypothesis was that high frequency terms in the catalog are the ones most frequently chosen in searches. The regular scatterplot of number of postings in the catalog versus the frequency in searching was checked and Pearson's correlation and Spearman's rank correlation coefficients were calculated. These data show that in general searchers actually tend to select the terms with a high number of postings for searching the catalog
