Representação descritiva da informação em bibliotecas: um estudo sobre os formatos de intercâmbio

Abstract

It is part of the organization of information in catalogs of libraries with a focus on descriptive representation and formats for the exchange of bibliographic data. Its main objective is to know the characteristics of the trajectory and the structure of the book description, in different exchange formats, making a comparison of these formats with the MARC 21 standard. In order to meet the proposed objective, the following specific objectives were delineated: identify formats for the interchange of bibliographic data between libraries, as well as their characteristics and guiding principles; emphasize the importance of adopting the rules of description and exchange formats for descriptive representation in library systems; and present the description structure of data in other exchange formats that resemble or differ from the current MARC 21 format. It is a bibliographic research, descriptive in nature and with qualitative approach. It shows that, in addition to the widely known MARC standard, other bibliographic exchange formats have been developed over the years. In addition, it brings out the scenario of consolidation of the main instruments, rules and standards of bibliographic description used in the automation of library catalogs, from the mid-1960s to the beginning of the 21st Century, revealing the efforts of information professionals in order to offer contemporary society access to bibliographic information in an organized and standardized way. Concludes that the MARC standard developed in the Library of Congress and the UNISIST Reference Manual, developed by UNESCO, guided the development of formats for the exchange of bibliographic data between the 1970s and 1980s. Especially, at this time, the formats: CALCO, UNIMARC, CCF, LILACS, CEPAL and the IBICT. Some of which are no longer used and others remain in force. From the 1990s, with the popularization of the Internet, the metadata standards for different contexts appeared on the web, highlighting the MARC 21 for Bibliographic Data and the Dublin Core metadata standard that, although not specific to the bibliographic context, has also been used in libraries. The comparison of bibliographic records with the current version of the MARC 21 has made it possible to learn about the particularities of each of these exchange formats.
