National conference of libraries held at Padua last February.
Descriptive cataloguing should become a minor concern for libraries as a consequence of the improved coverage offered by the various bibliographic utilities, in conjunction with the increasing number of digital documents. This has nothing to do with the idea that digital entities will catalogue themselves and that cataloguing standards are becoming unimportant since they do not apply to web sites and the rest. Such views, according to Gorman, are not only wrong but also noxious because, though masquerading as progressive, they are impeding progress. Instead cataloguers should aim at developing linking devices to connect packages of recorded knowledge and information, using their titles, edition statements, issuers, dates and any other known data, and adding formalized names and titles to those descriptions and to those digital entities that allow library users to retrieve and collocate those documents, and relating them to a location either physical or virtual.
However, it proves difficult for most librarians to abandon a system of bibliographic control that has been so successful and to adopt an entirely new set of concepts that will take full advantage of the new digital environment. The professional debate at an international level seemed so far more concerned with improvements needed within the established framework and hardly looked in any great depth at new concepts in cataloguing which are required if one wants to benefit from the intrinsic feature of a computer which resides in the ability to establish, coordinate and connect syntaxes of signs, as suggested by Serrai.
The need for a reassessment of the foundations on which cataloguing is based appeared with great evidence in the theoretical activities leading to the publication of the Functional Requirements for Bibliographic Records in 1998. On the one hand it was felt that many inconsistencies were caused by bibliographic representations heavily relying on ISBD, a standard which uses principles having little relevance in an electronic environment, having been defined with a concern for the printed versions of the national bibliography and the exchange of bibliographic record at an international level, rather than as a data model for the needs of the individual library catalogue. On the other hand, it is evident that because of the large size of many databases and the number of hits that most searches produce, users tend to be frustrated in attempting to use a catalogue and sometimes wonder if the complexity is really necessary, especially if compared to the apparent user-friendliness of the general web search engine.
The difference, according to Ayres, is a conceptual one which is already to be found in information retrieval where two basic types of searching have become established. These are pre-coordinate and post-coordinate. Cataloguing has so far always been a pre-coordinate operation and is based on what cataloguers do at the input phase, both as regards the description and the access terms. In particular, authority control (or entry point control as Gorman termed it already in 1977) in its present form is expensive to set up, to maintain and to use. Nevertheless, it is the foundation stone of sound cataloguing and a key factor in information retrieval and digital resources management. Again Ayres suggests that authority control be used to provide the link rather than the preferred heading, bearing in mind that from the user's viewpoint the preferred heading is the heading that he/she searches by and that in searching he/she wants the heading that he/she has thought about to be linked to the headings that he/she has not thought about. This means that the present authority control files will become linking files and that the entire procedure will implicitly be a post-coordinate operation. A fully developed electronic catalogue should be able to function in two ways, according to the specific needs of the user, providing intellectual (that is, access to the contents of library resources) as well as bibliographic control (that is, access to the physical packages in which content appears).
Eventually, catalogues should give access to cultural heritage information, not just of a bibliographic nature, which is now under distributed control, bridging the barriers to access that have been created by specific traditions of custody and documentation. The feasibility of such a vision largely depends on the capability of the system within which they are stored to interoperate with those around them, but above all it relies on the intellectual effort dedicated to build up some kind of semantic, political, human and legal interoperability, both nationally and internationally.
