Title: 510 - Citation/Reference Note (R)

The 510 tag of the MARC 21 bibliographic record 
contains the citation/reference, abstract, index, 
and/or review note information. The index and/or 
review must be a separate publication from the 
bibliographic item. This would include citations to 
reviews in professional journals, abstracting and 
indexing in a compilation of similar items, and 
other publications. This tag is repeatable and each 
source is entered into separate 510 tags. The text 
of the review or reference is not included in this 
tag; however, it can be incorporated into the 520 
summary note. 

The 510 tag is especially useful in establishing 
the location of reviews used in the selection of 
particular items. It will save time in locating 
reviews for items that could be controversial in 

Anglo-American Cataloging Rules (AACR2) 
control the structure and information entered into 
this note under General Rule 1.7B15 and rule 
4.7B15. RDA provides guidelines on 
recording relationships to related works.
