Next generation library catalogs and the integration of gazetteer information for geographical research
Julie Sweetkind-SingerAssistant Director of Geospatial, Cartographic and Scientific Data & ServicesApril 14, 2011
Agenda
• Standard library catalogs and cataloging standards
• Next generation library catalogs and what’s now possible
• Then what? Prediction of user wants.
Typical Library Catalog
MARC cataloging
Scale and cartographic extent given twice.
Geographic subjects combined with thematic information.
Authority file subject names – Library of Congress
451 fields trace back to the 151 field. No context is provided for the names.

Linking to other resources
Linking through authorized subject headings to results
potentially (or not) relevant.

If you knowwhat you are looking for,why are you looking?
And if you do not know what you are looking for,how can you find it?

Discovery
Next Generation Discovery EnvironmentOverarching Objective: To make it easier for patrons to discover and use the wealth of information resources held by providing a comprehensive place to search and browse. Specifically:
1.create a unified discovery interface to all library resources– OPAC, full text, finding aids, databases, web sites
2.create a feature-rich, highly interactive tool for searchers– search, browse, visualize, refine, expand, extract, one click
access
3.create a highly usable interface that achieves specific discovery tasks
– Using user-centered design, user research and testing, use metrics
4.create an extensible platform that be enriched over time with both more resources and more functionality
– personalization, alerts, integration with other toolsSlide courtesy Tom Cramer, SULAIR
SearchWorks
• http://searchworks.stanford.edu, Released in September, ’08
• Advantages:
1. Faceted navigation of results 3. Relevance ranking
2. Ability to add new indexes 4. Ability to integrate new services
(browse by call #, e.g) 5. Web 2.0 featuresSlide courtesy Tom Cramer, SULAIR
Features: facets, relevancy rankings, covers

Combining content
• Instead of Wikipedia or Freebase, add gazetteer information to the record.
• Pull geographic terms out and link to maps, databases, books, etc.
• Geolocate pictures in space by linking them to geographic information.
Future directions
• You like this? Maybe you’ll want this.• Predictive model like Amazon or clothing sites.
• Like-type items:• Rome: city-scale object in Italy – Here are more
like that.• Rome: 1st Century CE – More in that same time? • Rome: 16th Century – There are 15 maps in the
catalog of Italy at that time.
• How do catalogs predict what users want?
