  1. 2004 SLIS Board of Advisors Meeting, February 9, 2004 Research and Projects:Z, M, and Beyond! William E. Moen<wemoen@unt.edu>School of Library and Information SciencesTexas Center for Digital KnowledgeUniversity of North TexasDenton, TX 72603

  2. Z-INTEROP Z39.50 Interoperability Testbed • IMLS National Leadership Grant (2000) • Improve semantic interoperability through systematic testing and assessment of Z39.50 clients and servers, and online catalog implementations • Supported by Sirsi, OCLC, and Bookwhere/Web Clarity • Request for extension to pursue a Radioactive MARC Record approach for interoperability testing • Will lower barriers for individual libraries to participate • Innovative method that may be adaptable to other networked information retrieval applications 2004 SLIS Board of Advisors Meeting --February 9, 2004

  3. ZLOT Z39.50 Implementation in Library of Texas • Metasearch implementation allowing single search interface across library catalogs, TexShare databases, and other networked resources • Design and technical requirements for Resource Discovery Service for TSLAC (2001-2003) • Public release on February 2, 2004 • Functions: • Presence of local library in interface and for services • Default and user selection of target resources • Searching – Simple and advanced • Full-text access through transparent authentication • Get it! – Search online bookstores, submit request to initiate ILL • MARC record downloads (with permission) • Currently working on implementation of evaluation plan 2004 SLIS Board of Advisors Meeting --February 9, 2004

  4. Analyzing MARC Content Designation Use • Need an acronym or abbreviation! • Preliminary analysis as part of Z-Interop Project • Frequency count on 400,000 WorldCat records • Findings: • Moen 5 / 20 rule • 36 fields/subfields account for 80% of all occurrences • 19 fields/subfields may be sufficient for indexing to support title, author, and subject keyword searching • What extent do catalogers use the rich content designation available? • Can MARC records serve as an artifact of the entire cataloging enterprise, and if so, what do they reveal about that enterprise? • Submitted a proposal to IMLS for funding this research 2004 SLIS Board of Advisors Meeting --February 9, 2004

  5. Summary frequency results Total number of fields/subfields occurring in dataset = 13,849,499 Only 4% of all fields/subfields account for 80% of all occurrences or 96% of all fields/subfields account for 20% of all occurrences 2004 SLIS Board of Advisors Meeting --February 9, 2004
