037 Source of Acquisition

Field 037 contains source of acquisition information for the item or its reproduction.

If a stock number is present (subfield $a), source of stock number/acquisition information (subfield $b) is required.

Government agency assigned numbers that can be used for classification purposes are not carried in this field; they are contained in field 086 (Government Document Classification Number). The ISBN, ISSN, and publisher's and distributor's numbers for sound recordings, printed music, other music-related material, and video recordings are not carried in this field; they are contained in fields 020 (International Standard Book Number), field 022 (International Standard Serial Number), and field 028 (Publisher or Distributor Number), respectively. In addition, other standard numbers or codes published on an item are not accommodated in this field; they are contained in field 024 (Other Standard Identifier).

Archival identification or order numbers assigned by a distributor for computer files are recorded in this field. The original study number assigned by the producer is recorded in field 036 (Original Study Number for Computer Data Files).

The different and unrelated U.S. Government Printing Office stock numbers assigned by GPO to each issue of a serial are not carried in this field.

The field is repeated when there are multiple stock numbers and/or sources of stock number/acquisition associated with the item.

The National level record requirement for this field is Optional.

Field 037 is repeatable.

Subfield $b considerations

Content designator history:

In 1993, the scope of field 037 was redefined from "Stock Number" to "Source of Acquisition." Subfield $b was redefined from "Source of stock number" to "Source of stock number/acquisition" so as to include source of acquisition data previously recorded in obsolete field 265 (Source for Acquisition/Subscription Address). Also, as part of the redefinition of field 037, price and form of issue data previously recorded in obsolete field 350 (Price) is to be recorded in field 037.
