Harvard contributes metadata to POD: https://pod.stanford.edu

Incremental files are sent daily. 

Included as of Nov 2022:

  • All active bibs with active MARC holdings (from Alma system), as MARCxml. 
    • This includes NET holdings, which contain links to locally digitized resources available to the public, as well as a small amount of non-Harvard public resources
    • This includes FIG holdings, which contain links to material digitized through the Google Book Search project. Some links may point to HathiTrust. 
  • NOT included - bibs without MARC holdings, i.e.: 
    • No licensed e-journals, or activated e-journal collections such as Directory of Open Access Journals, or free e-resources managed as portfolios in Alma
    • No licensed e-books
    • No activated database records such as encyclopedias

General notes on data:

  • The data is published from Alma with the Linked Data enrichment option, which adds the $$0 (subfield zero) with linked data URIs when a heading is linked to an authority record. For detailed information, see https://developers.exlibrisgroup.com/alma/integrations/linked_data.
  • Private data is excluded per this Alma norm rule
  • Each bib record is embedded with fields from linked holdings records
  • Non-Latin parallel fields will be stored in linked 880 fields. MARC spec: https://www.loc.gov/marc/bibliographic/bd880.html
  • All fields from the same holding will have the same $8 value. 
  • All items from the same holding will have the $8 value of the linked holding.
