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.
