NASIGuide: Serial Holdings
Number and Code Fields

---

Only those codes that are usually editable are examined here. For a complete list of number and code fields, see the Concise MFHD on the MARC web site at http://www.loc.gov/marc/holdings/echdnumb.html.

Each code is discussed from one or more of three possible aspects, as applicable: conversion/migration, current coding, and/or retrospective coding.

010 - LIBRARY OF CONGRESS CONTROL NUMBER [Non-repeatable]

All coding

Seldom hand coded. If an imported holdings record identifier is an LC control number, and the user wishes to substitute his/her own institution's identifier in 004, the LC control number can move to 010. This would ordinarily be done through programming at the individual library. Cancelled or invalid LCCNs are given in subfield $z.

014 - LINKAGE NUMBER [Repeatable]

035 - SYSTEM CONTROL NUMBER [Repeatable]

All coding

Seldom hand coded. These are other areas (see 010, above) to move control numbers from 001 and 004. Because more than one type of control number can be moved to 004, there is a first indicator in 014 to identify the number as a holdings record ID (0) or bibliographic record ID (1). There is also a subfield ($b) to identify the source of the number. In 035, the NUC symbol appears, enclosed in parentheses, immediately before the number. Cancelled or invalid numbers are given in subfield $z.

Example

014     1              $a 8395872 $b OCoLC
035                     $a (UxU)3456789

020 - INTERNATIONAL STANDARD BOOK NUMBER [Repeatable]

022 - INTERNATIONAL STANDARD SERIAL NUMBER [Repeatable]

024 - OTHER (Definable) [Repeatable]

027 - TECHNICAL REPORT NUMBER [Repeatable]

022 - CODEN [Repeatable]

All coding

Seldom hand coded. All can be taken from the bibliographic record. The ISSN, in particular, might be wanted in the holdings record to link the holdings to citation databases (sometimes referred to as "hook to holdings").
