PUL Bibliographic Data Web Service (Bibdata)
Princeton University Library's own bibliographic data service at bibdata.princeton.edu. A Rails application (pulibrary/bibdata) that reads from Alma and re-serves bibliographic records, holdings, delivery and holding locations, libraries and events as JSON, plus periodic full dumps used to rebuild the Solr indexes behind the catalog. Location endpoints such as /locations/libraries.json are anonymously readable; staff operations sit behind Princeton CAS. The service prints its own deployed commit, deploy date and live index timestamps on its home page — more operational transparency than most of this cohort offers.
