MARC 9XX Local Data

MARC 9XX fields are reserved for local definition. The following 9XX fields are known to exist in Folger records. Many are, presumably, the result of other institutions' 9XX fields having remained in imported records. Those in bold are known to be in active use at the Folger.

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)
• 909 TIND reserved use: OAI-PMH information we

• 936 Random irrelevant information from OCLC internal use
• 938 Random irrelevant information from OCLC internal use

• 949 Used for record loads from GOBI. Details are maintained by Acquisitions.
• 950 Redundant call number or location information from old bulk loads
• 952 Records information normally in the 852, but for a now-returned long-term loan (so that the field label can be something other than "Folger copy note")
• 955 $q contains case and accession numbers from 1996 recon that doesn't appear elsewhere in the record (all are for post-1801 publications)
• 956 OCLC BibFormats says this is for local OCLC use, but all seven are notes about UMI microfilm in EEBO records (as of 2022-04-13)
• 960 Mostly normalized city of publication in ESTC records (sometimes redundant because Folger 752 has city in $d, but in most cases the 752 only has larger jurisdictions); a few have Harrassowitz order information
• 961 Harrassowitz order information

• 986 call number in EOCR records, but apparently always duplicated by 985

• 991 TIND reserved use: "SUPPRESSED"
• 993 "In-Proc" or "DeckB-Mod" in EOCR records
• 994 OCLC BibFormats says reserved for OCLC use; always seems related to EEBO vendor records

• 999 Usually "GOING IN" from bulk loaded records; occasionally a redundant LUNA link with outdated link text

Holdings records

• 952 ǂz: equivalent to 852ǂz so that label can be customized to display something other than "Folger copy note:" (added 2016-06-22 to accommodate loan item being made available to researchers)
