Since the Online Computer Library Center (OCLC) unveiled its WorldCat Local library catalog discovery layer in 2008, library instructors have debated how to incorporate this tool into their teaching. WorldCat Local's faceted searching brings both educational benefits and unexpected challenges to the classroom. Instructors frequently hold formal and informal discussions on such topics as which search features are most effective during teaching and which patron groups benefit most from this tool. The authors of this article surveyed instruction librarians at U.S. academic libraries that are using WorldCat Local in order to gather and organize this feedback. This article presents the findings of this survey. (Contains 2 tables.)
