- 8. The world’s libraries. Connected. • 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) GLIMIR
- 9. The world’s libraries. Connected. 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 Multilingual Bibliographic Structure Project
- 10. The world’s libraries. Connected. • 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 “Most appropriate” questioned

Connected. • 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 Translations Generated uniform title authority records will overcome most of these differences without needing to edit individual records

Notes de l'éditeur
- There are more than 300 million records in WorldCat today representing holdings of the world’s libraries. There are also another 200 million articles. Of the 300 million, more than half are in languages other than English.
- The 300 million records are clustered into works. The records may be in just one language of cataloguing or they may have a mixture of language of cataloguing, e.g. subject heading in more than one language. Parallel records may exist, i.e. records in different languages of cataloguing describing the same resource.
- The existing architecture is bibliographicrecord centric. There may be links to author and subject authority records. The work, manifestation and content clusters only contain identifiers, no metadata at present.
- Three complementary initiatives are in progress concerning multi-lingualism and WorldCat.
- The first project – generation of metadata at work level to make better presentations.
- The GLIMIR project creates clusters of parallel records for the same manifestation (manifestation cluster) and also clusters for the same content, though the form may be different (print, microform, digital). We are in the process of trawling thorugh the database to make these clusters.Only the part in blue will be changed by the multi-lingual bibliographic structure approach
- Concerning correcting records coded as “und” = “undetermined”, we expect that we can correct about 7 million by searching for the same title string in other records.
- Currently when the short list and full displays are created, the system selects the most appropriate record for display. The most appropriate record is determined by its size and the number of associated holdings and it was envisaged to extend this to include the language of cataloguing. But we think we can do much better by questioning the “most appropriate record” concept.
- Here the first record is catalogued in German but has no significant German content – no subject headings and no notes. There are other richer records that could inform the user better.
- Hyrid records also mean that significant linguistic information may be buried in other records.
- This record has subject headings in 3 languages.
- Build the information to display to users from all available records and show them all relevant holdings. Do not display just one selected record from the work set. Cataloguers too will benefit from this, being able to drill down to actual records where appropriate.
- This is the theoretical bibliographic structure that will no longer be bibliographic record centric but work centric. All information – authors, notes, summaries, subject headings will be flagged with the language of cataloguing.
- The work level metadata will be tagged with language for each data element.Instead of always showing the data from the main title in the record, the alternative script fields may be chosen for display, depending on what the system can determine about the user, e.g. from IP address range or expressed preference.Worldcat.org already includes the ability to change language of display, but the numbers of fields that change will be enhanced and the tabulation of several displays will be improved.Consolidate holdings from all records that re applicable to a display (work, content, manifestation level)
- An Iceland Fisherman, original in French displayed in English UI with Translations table.
- Same record with Chinese interface
- The Grand Design; English in Italian UI with Translations table.
- Same in Japanese interface
- Instead of working directly with lesser quality records to improve the quality in WorldCat and instead of working with the long tail, we are turning our attention to the most important works and working ways to use the good records to improve the quality.
- Translated titles not always consistent, causing work grouping failure. Sometimes:caused by titles without sub titles, caused by different forms of uniform title, i.e. in Gujarati and in English (several forms)caused by inverting the titles, by placing the name Gandhi before “Autobiography”. Some figures: French – 15 records, 6 work sets; German - 9 records, 9 work sets; Italian 7 records, 5 work sets; Spanish 8 records, 4 work sets
- VIAFConsolidated display – shows work with expressions summary.
- This is the full expressions summary for the work Pêcheurd’Islande
- VIAFFull display – whos all the expressions, e.g. different translations with the title and the translator and the earliest determined publication date
- These records will enrich VIAF. There is no risk of generating bad records. The translation records will include both the translated title and the translator (both are not usually included in existing records in VIAF)Most of the expression records will be new to VIAF.
- The newly generated records will be available in the formats as distributed by VIAF.
- Just think. How many of the 150+ million records that are for non English language works are actually translations of English language records. And how many of the English language records are also translations? It could be as high as 25%? Once we have these records generated, it will open many new possibilities.Also, we know we have 300 million records, but how many real resources do we have? GLIMIR will produce these figures. We are just starting…
