I am Chief of the Policy and Standards Division (PSD) at the Library of Congress. That division of 28 outstanding people is responsible for creating and distributing various authoritative cataloging tools, including LC Rule Interpretations/LC Policy Statements, LC Classification schedules, LC Subject Headings, and other cataloging and acquisitions documentation, as well as the Web products, Cataloger’s Desktop and Class Web. They also provide database maintenance for LC's bibliographic, authority, and holdings records. I serve as the Library of Congress representative on the Joint Steering Committee for Development of RDA: Resource Description and Access (the new cataloging code) and on the Virtual International Authority File (VIAF) Project, and led the IFLA work that produced the Statement of International Cataloguing Principles (ICP). Along with Elaine Svenonius and Tom Delsey, I served as one of the consultants that developed the conceptual model for IFLA’s Functional Requirements for Bibliographic Records. I have been at the Library of Congress for the past 17 years, including several years leading the successful effort to move to an integrated library system. Prior to working at the Library of Congress, I worked at the University of Hawaii and the University of California, San Diego (including Scripps Institution of Oceanography Library and the Central University Library), with a short time teaching at UCLA following my doctorate. My publications have focused on cataloging theory and practice, authority control, bibliographic relationships, conceptual modeling, and library automation. My dissertation on bibliographic relationships has been a source for conceptual designs of computer-based systems for bibliographic control.
