Automated Enrichment of Master Records
25
Reducing Duplicates – An Improved Algorithm First production run, May 18, 2009 Running small files (500 – 3000) Statistics for May & June 2009 33,023 records processed 1,777 duplicates removed (5.7%) 846 records deferred for manual review
26
Reducing Duplicates – An Improved Algorithm Full production run, Feb. 2, 2010 Entire Database, beginning with OCN #1 Statistics so far: 7.5 Million records processed Almost 650,000 records removed Unique fields from deletes merged into the master record The exception to this is non-Latin fields. We try to ensure that all non-Latin fields are in the retained record even if they are not on the list of mergeable fields.
27
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”
28
Total Replaces = 108, 766
29
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”

The interdisciplinary studies enhancement helps libraries: Define their own unique interdisciplinary studies area Easily navigate through the OCLC Conspectus identify titles in multiple subject areas Compare interdisciplinary studies collection against peer libraries identify overlaps and gaps Limit an analysis by Category and/or Subject in addition to Division Save Subject Profiles and have them available for use in the future Demo: http://vidego.multicastmedia.com/player.php?p=u3t34bs7http://vidego.multicastmedia.com/player.php?p=u3t34bs7 Interdisciplinary Studies Analyses

WorldCat Quality– Let’s Probe What “Quality” Really Means Local Group Global
36
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 http://www.oclc.org/us/en/reports/onlinecatalogs/default.htm
37
Recommended enhancements to WorldCat Total end-user responses End-User Results: Recommended Enhancements 4 Librarian/Staff Results: Highlighted Differences 14 1
38
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.

WorldCat Registry – Enabling Services Local Group Global

Metadata about Libraries WorldCat Registry A repository of metadata about libraries: Location Contacts Policies Links
41
WorldCat Registry Value Proposition The WorldCat Registry allows your library to: Provide direct linking to local library services over a variety of OCLC products including WorldCat.org and WorldCat LocalWorldCat.orgWorldCat Local Create and manage a profile that centralizes and automates information sharing with vendors and OCLC Receive a free benefit of greater internet visibility regardless of the OCLC membership

The Vision Achieve web scale for KB services Move the KB to the cloud Provide KB services through an API model to: Provide a central platform for KB data management Allow read and write access to the KB within OCLC services Allow read and write access to the KB for external services The KB can be managed in one place, but exposed anywhere

WorldCat Growth – The Value of the Cooperative Local Group Global
63
The Value of the Shared WorldCat Network An incomparable source of library- standard records to support local or group library discovery and collection management. Record supply Bibliographic and holdings data from more than 70,000 libraries, underpinning delivery of library collections, resource sharing, and collection analysis. Registration of holdings An infrastructure utilizing library standards for description, name authority control, classification, and terminologies. Knowledge organization
64
Record Supply: Where do WorldCat records come from? The cooperative provides the content. The cooperative activity provides the value.

Cataloging: Key to All OCLC Services WorldCat Find & Get Items Discovery Holdings & Availability Resource Sharing Bibliographic Descriptions Cataloging & Metadata Services Library Descriptions WorldCat Registry
