Expert Community Experiment Experiment to test “social cataloging” with OCLC’s expert community (modeled on Wikipedia) Interest and motivation from WorldCat Local libraries that want to use WorldCat Local as their “database of record”

Total Replaces = 108, 766

What are they saying? “I am loving the ability to fix typos, add more subject headings, etc. Some of which were things I would do locally but were too much of a hassle to fix at the oclc level.” “Thank you so much for the opportunity to participate in the community enhancement experiment! Having the ability to correct typos, flesh out minimal…cataloging…is really wonderful. I hope the experiment works out well … -- I would love to see it made a permanent feature”

WorldCat Quality– Let’s Probe What “Quality” Really Means Local Group Global

Online Catalogs: What Users and Librarians Want End-Users expect online catalogs: to look like popular Web sites to have summaries, abstracts, tables of contents to help find needed information Librarians expect online catalogs: to serve end users’ information needs to help staff carry out work responsibilities to have accurate, structured data to exhibit classical principles of organization

Recommended enhancements to WorldCat Total end-user responses End-User Results: Recommended Enhancements 4 Librarian/Staff Results: Highlighted Differences 14 1

What did we learn? End-user focus group results Key observations: Delivery is as important, if not more important, than discovery. Seamless, easy flow from discovery through delivery is critical. Summaries and tables of contents are key elements of a description Improved search relevance is necessary.
