Harvard contributes metadata to POD: https://pod.stanford.edu
Included as of Feb 2022: all active bibs with active holdings (from Alma system) as MARCxml
Portfolios not yet included (e.g. licensed e-resources)
General notes on 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.

| m | current location code | see above, for location |
| 7 | call number type | classification scheme |
| n | call number | entire call number from 852 compressed into single subfield |
| d | Enum A | |

| f | Chron I | |
| g | Chron J | |
| 3 | description | usually only present for serials / multi-volumes |
| q | item status | binary value: in place (1) or not in place (0) |
