C.1. General Rule [Formerly C.0]
Form for Arabic Numerals:
Objective. The objective of this rule interpretation is to normalize the method of transcribing numbers used in access points of bibliographic records to achieve consistent results in filing accomplished either by computer or by person (the LC computer filing program reflects U.S. transcription practice only). In the LC computer filing program, commas are discounted but periods and spaces are not. Thus, 1,512 and 1512 are treated the same but 1.512 is treated as a decimal and 1 512 is treated as two distinct numbers separated by a space. Thus, consistent treatment with respect to filing depends on consistent, normalized transcription in certain cases.
1. Access points. For purposes of this rule interpretation, access points are headings, uniform titles, titles proper, series titles, and title added entries.
a. Transcribing numbers given in arabic numerals. Use U.S. practice as described in The Chicago Manual of Style, sections on decimals (8.17) and on the use of the comma (8.64).
1. Decimals. Use of a period instead of a raised dot or a comma.
2. Figures of one thousand or more. Use commas.
Do not, however, use a comma when a figure is judged to be a literary device, commonly written without the commas or when it is judged the comma would be inappropriate.
Note: Apply these provisions for access points also to any title recorded in a bibliographic record (e.g., in a parallel title, in a variant title note, in a formal contents note).
b. Updating existing records.
1. Authority records.
a. Names. Update any automated name authority record that contains a number in any heading or reference that does not reflect the practice described in this rule interpretation.
b. Series. Update any AACR2 series authority record that contains a number in any heading or reference that does not reflect the practice described in this rule interpretation.
2. Bibliographic records.
a. Do not update pre-1981 non-MARC records to reflect this rule interpretation.
b. MARC records and post-1980 non-MARC records. Update any bibliographic record that contains a number in an access point that does not reflect the practice described in this rule interpretation.
2. Other portions of the record. Use U.S. practice as described in The Chicago Manual of Style, sections on decimals (8.17) and on the use of the comma (8.64). Note that section 8.64 contains exceptions applicable to page numbers, addresses, etc.
