Information taken from sources other than those prescribed for a particular area of the bibliographic record is to be enclosed in square brackets.

Chief source of information for scores

Chief source of information = title page.

° The chief source of information for printed monographs (including scores) is the title page.

° If there is a title page you must use it.

° If the title page is a "list title page," use either the list title page, cover, or caption as the chief source, whichever provides the most information.

° If there is no title page or without a title page applying to the whole work, use the title page or title page substitute as the chief source of information.

° Use the part of the item supplying the most complete information (excluding a separate book jacket) in this order of preference:

° caption

° cover ¹

° colophon

° other preliminaries

° other sources

° Specify the part used as a title page substitute in a note (see 2.7B3).

° If no part of the item supplies data that can be used as the basis of the description, take the necessary information from any available source.

° If the information traditionally given on the title page is given on facing pages or on pages on successive leaves, with or without repetition, treat those pages as the title page.

¹ Unless the "cover" is made of a thicker, thinner or different color paper than that on which the music is printed, consider it to be the title page. MCB v. 16, no. 11, p. 5.
Richard Smiraglia in Describing Music Materials, 1997, p. 2: "... decorative title pages are not the same as covers. ... A colorful title page is not necessarily a cover."

Chief source of information for sound recordings

type of recording	chief source
disc	disc and label 2    3
reel-to-reel tape	reel and label 2
tape cassette	cassette and label 2

²The "label" is defined as permanently affixed paper, plastic, or other material. If there are labels on two or more sides, treat all as a single source.
³For CDs, which have no label per se, consider the information appearing on the disc itself to be the label. Consider any information on the insert that can be seen through a closed cassette case or jewel case to be on the container.

When the label lacks a collective title but one is found on the container or accompanying material, use either of these sources as the chief source and indicate that in a note.

Lacking a label, use the following sources in this order of preference:
   ° accompanying material
   ° container (sleeve, jewel box, etc.)
   ° other sources

When a source other than the chief source (disc or label for discs or cassette or label for cassettes) is used as the chief source, indicate that in a note.
