Subfield ‡b contains the name of the place where the reproduction was made. When more than one place is given, subfield ‡b is repeated.

Subfield ‡c contains the agency responsible for the reproduction. If more than one agency is simultaneously responsible for the same reproduction, subfield ‡c is repeated.

Subfield ‡d contains the date when the reproduction was made. For continuing resources, the beginning and ending dates of the reproduction are given when available.

Subfield ‡e contains any physical description information about the reproduction. It normally contains the number of physical pieces and the dimensions of the reproduction. The polarity, when negative, is recorded in subfield ‡e as other physical details following the number of pieces and preceding the dimensions. For continuing resources, the number of microfilm reels, microfiches, etc., is recorded only when the microform set is complete.

Subfield ‡f contains the series to which the reproduction belongs. Subfield ‡f is always enclosed in parentheses.

Subfield ‡m contains the sequential designation and/or dates of publication of the original issues that have been reproduced.

Subfield ‡n contains a note pertaining to the reproduction. If more than one note is needed, subfield ‡n is repeated.

Subfield ‡3 contains information that indicates the part of the described material to which the field applies. When separate holdings records are made for each part of a bibliographic item, each record may contain a field 843 that contains a subfield ‡3 to specify the part to which the note applies. When holdings for all of the parts of a bibliographic item are contained in one holdings record (and there is no 863-865 Enumeration and Chronology field), subfield ‡3 may be used whenever a data element in field 843 differs for a specified part of the item.

Subfield ‡5 contains the MARC code of the institution or organization that holds the copy to which the data in the field applies. It is used for institution-specific information that may or may not apply to the universal use of the holdings record. See organization code sources for a listing of sources used in MARC 21 records.

Subfield ‡7 contains fifteen character positions (designated 0, 1-4, etc.) that contain coded information pertaining to the reproduction. The coded data elements correspond to those in the 008 field of the MARC 21 Format for Bibliographic Data. The data elements are positionally defined. All character positions must contain either a defined code or a fill character (|).

Form of item

Subfield ‡7/14 contains a one-character code that specifies the form of material for the reproduction in hand. The appropriate code found in 008/23 (Form of item) of the MARC 21 Format for Bibliographic Data for books is used. 843     Microfilm.‡bWashington, D.C. :‡cLibrary of Congress, Photoduplication Service,‡d1990.‡e1 microfilm reel ; 35 mm.‡7s1990dcuna 843     Microfiche.‡b[New York :‡cNew York Public Library,‡d197-?]‡e4 microfiches: negative.‡7q19701979nyunb 843     Microfiche.‡m1961-‡bWashington :‡cU.S. G.P.O.,‡d1990-‡emicrofiches: negative.‡7c19619999dcuarb 843     Microfilm.‡m1962-1965.‡bAnn Arbor, Mich. :‡cUniversity Microfilms International,‡d1988.‡e1 microfilm reel ; 35 mm.‡7d19621965miuuua Subfield ‡7 is always the last subfield in the field.

Subfield ‡8 contains data that identifies linked fields and may also propose a sequence for the linked fields. Subfield ‡8 may be repeated to link a field to more than one other group of fields.

The structure and syntax for the field link and sequence number subfield is: ‡8<linking number>.<sequence number>

The linking number is the first data element in the subfield and required if the subfield is used. It is a variable-length whole number that occurs in subfield ‡8 in all fields that are to be linked. Fields with the same linking number are considered linked. A linking number of "0" (zero) is not used in this field.

The sequence number is separated from the linking number by a period "." and may be optional. It is a variable-length whole number that may be used to indicate the relative order for display of the linked fields (lower sequence numbers displaying before higher ones).

Subfield ‡8 is always the first subfield in the field when it is used.
