Input Conventions  (76X-79X Linking Entry Fields - General Information)

The following input conventions for the 76X-79X fields are discussed below:

Establishing a link

Punctuation

Order of subfields

Spacing

Initial articles

Display constants

Establishing a link:

Links are generally established reciprocally in related bibliographic records.  A linking entry field links to a related item which may be represented in a file by a record.  When related records exist, each record may contain a corresponding linking entry.  In some cases the reciprocal linking entries use the same field tags, in others they have corresponding field tags.  The reciprocal field tags are as shown below:

The definitions of the second indicator values for reciprocal fields 780 and 785 are also reciprocal as shown below:

Punctuation:

Subfield $a ends with the punctuation contained in the 1XX field of the related record.  The linking entry fields do not end in a mark of punctuation unless an abbreviation, initial/letter, or other data that ends with a period is present, or subfield $a is the last subfield.

Examples:

780  00  $tJournal of the Australian Mathematical Society. Series A, Pure mathematics

780  00  $aAssociation of American Library Schools.$tDirectory of American Library Schools$w(DLC)sc#84007016#

Order of subfields:

The control subfields should be given in the following order, when more than one is present:

subfield $6, then subfield $3, and subfield $7 recorded last

Spacing:

If subfield $a contains a corporate or meeting name, each subordinate unit is preceded by two spaces following the mark of punctuation.

Example:

780  00  $aLibrary of Congress. Division for the Blind and Physically Handicapped.$tNews

When a title in subfield $t consists of a main title and section title with or without a numerical designation, two spaces are given between the main title and the numerical designation or section title.

Example:

785  00  $tJournal of polymer science. Part A, General papers

Initial articles:

Initial articles in the entry of the related record are omitted in linking entry fields except in entries where the intent is to file on the initial article.

Examples:

Display constants:

The display constants that may be used when generating notes from the linking entry fields are described in the specific field descriptions.
