Metasearch applications providing single search interfaces to diverse and distributed resources have been rolled out in the past few years. These applications have the potential to reduce barriers to information discovery and access. Systematic usability assessment of the metasearch applications have yet to be undertaken. This presentation will explore issues of usability assessment and suggest key challenges in conducting robust usability assessment for this distributed search environment.

Dr. William Moen is a Fellow in the Texas Center for Digital Knowledge, and an Associate Professor in the School of Library and Information Sciences, University of North Texas. His Ph.D. is from Syracuse University where he wrote his dissertation on the development of the Z39.50 information retrieval protocol standard.

He teaches courses on the organization of information, metadata and networked information organization and retrieval, and Z39.50. His research program includes the organization of networked resources; distributed searching and networked information retrieval; interoperability testing; and the development and implementation of technical standards.

Dr. Moen is principal investigator for the ZLOT Project, the Z39.50 Implementation Component of the Library of Texas, funded by the Texas State Library and Archives Commission. The focus of the project is to define, plan, and assist in implementation of a Resource Discovery Service for the Library of Texas.

He is also chair of the NISO Standards Committee that drafted the American National Standard Z39.50 Profile for Library Applications. And the Institute of Museum and Library Services awarded him a National Leadership Grant to establish a Z39.50 interoperability testbed.
