WorldCat Today • Resources in nearly all languages • Contributed by more than 20,000 libraries worldwide • More than half the database is for works not in English The world’s libraries. Connected.
WorldCat Today • Bibliographic Records • Hybrid records • Parallel records • Clustered at Work level (FRBR) The world’s libraries. Connected.

Work Level Record: Objective Create a landing page summarizing content for a work The world’s libraries. Connected.
GLIMIR • The Content Cluster • Enables better work record displays by reducing the number of lines that display for large works • Enables a choice of format and presents the formats that could be acceptable substitutes • Consolidates holdings for identical content • The Manifestation Cluster is important • Consolidates holdings at manifestation level • In the short term allows the record catalogued in the language of the interface to be chosen for display • Reduces apparent duplication • Allows a more accurate count of the number of manifestations in WorldCat (as opposed to the number of records) The world’s libraries. Connected.
Multilingual Bibliographic Structure Project Creates true multi-lingual displays • At work and manifestation levels • Using all available data instead of “most appropriate record” • Generates data Corrects many of the 28 million records coded “und” Better control and linking of translations Input to refinement of work clusters Smarter data storage The world’s libraries. Connected.
“Most appropriate” questioned • Worldcat.org selects the most appropriate record to show to a user as representative of the work in the short result list and beyond • The end result will not be very satisfactory from a multi- lingual viewpoint… here’s why The world’s libraries. Connected.

Multilingual Bibliographic Structure Project • Work level data, mined from all associated bibliographic records will be displayed supplemented with expression / manifestation level data as the user drills through the short to fuller versions of the metadata. End user interface will show works and manifestations not bibliographic records; the cataloguing client will also show bibliographic records The world’s libraries. Connected.

Great works are translated • The cream of the world’s cultural and knowledge heritage is shared by being translated • WorldCat contains many rich cataloguing records for these translations GOAL: Data mine the really good records to improve clustering, presentation, authority records and linked data The world’s libraries. Connected.
Translations • Inconsistencies causing work clusters to be incomplete & less than optimal search results • Titles without subtitles • Different forms of uniform title or missing uniform title • Inverted title • Different coding of original and translated information Generated uniform title authority records will overcome most of these differences without needing to edit individual records The world’s libraries. Connected.
Generate uniform title authority records • Improve FRBR work groups • Made by data mining • Contribute to VIAF • Diffuse via VIAF as linked data • Possibility to create web page / web service The world’s libraries. Connected.
