- 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
- Subject access to bibliographic data supported by knowledge organization systems, such as subject headings and classification, plays an important role in ensuring the quality of library catalogues. It is generally acknowledged that users have a strong affinity to subject browsing and searching and are inclined tofollow meaningful links between resources. Research studies, however, show that library OPACs are not designed to support or make good use of subject indexes and their underlying semantic structure. A project entitled OPAC semantici was initiated in 2003 by a number of Italian subject specialists and the Italian "Research Group on Subject Indexing" (GRIS) with a goal to analyse and evaluate subject access in Italian library catalogues through a survey of 150 OPACs. Applying the same methodology, a follow-up survey to assess whether any improvement had taken place was conducted five years later, in spring 2008. Analysis of these two surveys indicated that there was a slight improvement. The authors discuss the results of these two surveys, analyse the problems in subject searching in OPACs and explain the recommendations for subject searching enhancement put forward by GRIS. Using the example of Italian OPACs, the authors will attempt to outline some requirements for a subject searching interface and explain how this can be achieved through authority control.

- Abstract
- Enhancing content description of specialized resources, particularly astronomical resources, is a matter that is still unresolved in library and information science. In this paper, the authors outline deficiencies in some fields and elements of cataloging standards for description of historical astronomical resources, mainly star atlases and catalogs. Furthermore, they review their recent proposal of astronomical parameters for a better description and propose an approach for accommodating these parameters in the current criteria of MARC 21, the International Standard Bibliographic Description, and Resource Description and Access. Fourteen new parameters are considered, and recommendations are provided to standards developers for the addition of elements to accommodate attributes of celestial cartographic resources. This would improve bibliographic records for such resources in astronomical libraries' OPACs, which will have a beneficial effect on information retrieval.
