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:

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.


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


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


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.


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.


Related record:

245  04  $aThe Journal of microbiology.

Linking entry:

780  00  $tJournal of microbiology

Related record:

110  1#  $aEl Salvador.$bDirección General de Estadística.

245  10  $aResúmen estadístico de la República de El Salvador.

Linking entry:

780  01  $aEl Salvador. Dirección General de Estadística.$tResúmen estadístico de la República de El Salvador
