Title
XML and MARC : which is "right"?
Source
Cataloging and classification quarterly. 32(2001) no.1, S.81-90

Abstract
This article explores recent discussions about appropriate mark-up conventions for library information intended for use on the World Wide Web. In particular, the question of whether the MARC 21 format will continue to be useful and whether the time is right for a full-fledged conversion effort to XML is explored. The author concludes that the MARC format will be relevant well into the future, and its use will not hamper access to bibliographic information via the web. Early XML exploratory efforts carried out at the Stanford University's Lane Medical Library are reported on. Although these efforts are a promising start, much more consultation and investigation is needed to arrive at broadly acceptable standards for XML library information encoding and retrieval.
