When to use
The preferred title (recorded in the 130) is required to break a conflict among common titles or resources with identical titles by employing one of the following qualifiers, place of publication, publication date, edition statement, type of publication, and sometimes multiple qualifiers (place and date).
With most serials, the title proper is itself the preferred title (and, absent a creator) the authorized access point. But when the authorized access point [title proper] for a serial work being cataloged is found to be identical to an access point [the title proper] already in the catalog that represents another work, something must be added to the access point to distinguish it. Usually, these additions are made in the form of parenthetical qualifiers. (CCM: 5.2.5)

130 0# $a Precipitation in the Tennessee River Basin (Annual)
130 0# $a In focus (Indianapolis, Ind. : 1989)
CONSER does not specify a preference in the choice of qualifier and discourages using the corporate body as qualifier except when the title proper consists solely of very general words indicating the type publication of periodicity as well as when the place has already been used as a qualifier for another work.

When the preferred title or qualifier (130) is not needed
No evidence there are other works with the same title
Where the combination of the corporate body and title proper do not match that of another record
When a serial consists of a common title and section title and the combination of both does not match that on another record
When the title being cataloged matches only a Variant Title (field 246) found in another record
When a serial changes from one media type to another and does not fall into any other category requiring an addition to the authorized access point
When a resource is republished or reproduced (as a text, as a microform, as large print, as a Braille edition, as a digitized reproduction, etc.Form of Preferred Title
Preferred title in MARC field 240
Access points that include a corporate body creator are in conflict only when the authorized access point for another work has both the same creator and the same title proper. Make additions to the authorized access point for a serial entered under corporate body when both the corporate body and title proper are the same as that found on a record for another work. The authorized access point (with qualifiers), in this situation, is input in field 240.
