Libraries continue to struggle with cataloging e-books, managing records from multiple sources, customizing URLs, merging records from multiple sources, and managing updates and deletes. Holly Tomren, Drexel University, and Sarah Haight Sanabria, Southern Methodist University, will describe their processes for cataloging e-books along with their experiences during the beta pilot test of cataloging e-books using the WorldCat knowledge base. David Whitehair, OCLC, will provide additional information about the new WorldCat knowledge base functionality. Please join us for a lively discussion and share your experiences related to managing e-book cataloging.
