This paper provides an update on the revision process undertaken to produce a new, relevant, and useful ISBD(S) (International Standard Bibliographic Description) standard for describing serial publications in both print and electronic formats. Highlights include: the concept of "integrating resource," i.e., a bibliographic resource that is added to or changed by means of updates that do not remain discrete and are integrated into the whole; modification of the definition for serial; determining what is a major title change; the process followed by the Working Group to revise the existing ISBD(S) standard; and the new concept of the ISST (International Standard Serial Title), including related issues that need to be addressed. The following benefits of developing an up-to-date serials standard are summarized in conclusion: increased opportunities for national and international record sharing; elimination of confusion for users and catalogers trying to identity and locate material; and use of one record for national library catalogs and reporting of the international ISSN (International Standard Serial Number) agency.
