  2. 2. http://www.biodiversitylibrary.org/browse/map
  3. 3. Data for Geocoding:Library catalogue records (MARC21) Subject Heading from library catalogue: Hunting – Africa Animal behavior <- Expressed as MARCXML $zphrases are extracted & submitted to Google Maps API &GeoNames API
  4. 4. Admin screens for data editing, adjustment
  5. 5. Limitations: False positives• Not many from MARC records – Curated data, marked up• Many in automated data mining
  6. 6. Limitations: Name variations &centroids X
  7. 7. Limitation: Historic names
  8. 8. Additional details Geocoding LCSH in the Biodiversity Heritage Library Reusing metadata generated through years of cataloging practice is a natural and pragmatic way of leveraging an institution’s investment in describing its resources. Using Library of Congress Subject Headings (LCSH), the Biodiversity Heritage Library generates new interfaces for browsing and navigating books in a digital library. LCSH are grouped into tag clouds and plotted on interactive maps using methods available within the Google Maps Application Programming Interface (API). Code examples are included, and issues related to these interfaces and the underlying LCSH data are examined.
