MARC 9XX Local Data

MARC 9XX fields are reserved for local definition. The following 9XX fields are known to exist in Folger records. Those reserved for TIND use are essential to the functioning of the catalog.

Bibliographic records

NB. per OCLC BibFormats "Fields 901-907, 910, and 945-949 have been defined by OCLC for your local use and will pass OCLC validation. The remaining 9xx fields may also be locally defined by your library, but may not pass OCLC validation."

• 900 Most say "(c) Casalini Libri, CP 12, 50014 Fiesole (Italy). Email: info@casalini.it" but 31 (all 2004 or earlier) have $aAUTH or $aAUTH$bTOC (as of 2022-04-13)

• 902 Only a few instances, most (all?) are obsolete local notes (e.g. "Folger has v. 2 t. 1 and v. 3. More on order" but as of 2022-04-13 we also have v.4)
• 903 Only a few instances, some (all?) are obsolete or redundant local notes (e.g. "Copy 2 bd.w. B5888 copy 2" but both copies are accounted for on another bib)
