RDA defines Other title information as a word, character, or group of words or characters that appears in conjunction with, and is subordinate to, the title proper of a manifestation (e.g., subtitle).
Is required only if it provides clarification or support to the Title proper that otherwise might appear misleading without the Other title information (CONSER) or when the statement of responsibility is embedded in the Other title information (RDA).
Record Other title information in the 245, subfield b only from the same source as the Title proper (RDA 2.3.4.3). Statements that would normally constitute Other title Information that are found only on other sources may be given in a note.
⮚Subtitles
The most common type of Other title information is the subtitle. In order to decrease the need for maintenance given the frequency by which subtitles change, CONSER practice is to transcribe the subtitle judiciously and when it provides clarification to the title proper.

⮚Parallel Title Proper and Acronyms
CONSER practice is to record in MARC field 245, subfield b when a Parallel title proper is present and for acronyms or initialisms (CCM: 6.1.4.d) that are embedded in the Title proper.

⮚When the Statement of Responsibility is Embedded in the Other Title Information
CONSER practice is to follow RDA and transcribe the Statement of responsibility as Other title information (245, subfield b) when the SR is linked to or embedded in the Title proper.

⮚Changes to the Other Title Information (Subtitle, etc.)
A change in Other title Information does not constitute a major change, i.e., it does not warrant the creation of a new description. In most cases, such a change is ignored, or a note, Subtitle varies, may be given. (CCM: 6.7.1)
