One of the first publications on BHL was initiated by Chris Freeland (BHL Technical Director) and the tech team at the Missouri Botanical Garden (MOBOT) and published in the then still pretty new online journal, Code4Lib Journal. I also contributed enough for author credit.
The map, created using the methodology outlined in the article, was a feature of the BHL website for a number of years.

Abstract: 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.
