Internet cataloging facilitates access and adds value to Internet resources by helping the user find needed resources with relative ease and in a timely manner. It attests to the value of traditional library principles of organizing information and the value of catalog librarians' experience and skills. This paper explores the suitability and applicability of current cataloging rules and tools for Internet resources, and indicates how traditional cataloging methods should evolve. Creating, organizing, and providing access points for Internet resources, and maintaining the currency, persistence, and validity of an Internet catalog present serious challenges for catalog librarians. The paper also discusses OCLC's InterCat Project, an online catalog that uses traditional cataloging standards, the University of Nebraska-Lincoln's (UNL) Internet Resources Catalog, other library World Wide Web databases, providing Web access through the online public access catalog, and Internet catalog maintenance. Six figures show an OCLC InterCat Record, UNL HTML Work-Form; UNL Internet Catalog Record; UNL Internet Catalog Database; UNL Internet Catalog Search Mode; and OCLC's PURL (Persistent Uniform Resource Locator).
