Key:

• Rule numbering and titles taken from DCRM(B) first printing 
• Module code in parentheses before rule number indicates location of original text to be changed; module code after description of needed change indicates that the change has been made in that module; module code after plus "n/a" means change has been verified as not applicable to that module
• Because subsequent printings are based on an entirely new text supplied by BSC but Cataloger's Desktop is updated manually, there is occasionally a discrepancy between print and online that is to be noted and CD to be given the correction
• Additions to text are shown underlined; deletions are shown struck through
• Codes:
• {B, B1}, B2, B3, B4 = Books, first through fourth printings; "not done" indicates that the intended change was inadvertently not made 
• C = Cartographic
• G = Graphics
• M = Music
• MSS = Manuscripts
• S = Serials
• CD = Cataloger's Desktop

Variations requiring a new record

(MSS n/a)

1. (B)(S) Change uppercase small caps "a" to lower case in chapter title; headers are okay as is. (G) (M, umm don't get this; ah, okay; was already done, which is perhaps why I didn't understand)(C - it just means the word "A" in the title should be small cap not big cap - it is not a big enough word to "deserve" the big cap) (B4)

E1.2.

1. (B) Change "bibliographic format" to "bibliographical format" to match usage elsewhere in text. (C) (M) (B4)
