Geocoding LCSH in the Biodiversity Heritage Library
The Code4Lib Journal published Geocoding LCSH in the Biodiversity Heritage Library in issue number 2 back in March, but for some reason my alert for LCSH just brought it up today, apparently based on a changed comment which I don’t see. The abstract states
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.
One of the points I particularly liked was the importance of good cataloging data to start with. Computers can do a lot to manipulate data, but it has to be created before it can be manipulated.
