RE: USE OF TRAILING X IN CALL NUMBERS

DATE: APRIL 11, 1991/rev. FEB 1994

POLICY: Trailing X is used in call numbers for which there is data base copy with LC classification call numbers. The trailing X may also be used in original cataloging in special situations. The position of the trailing X in call numbers must be consistently associated with the cutter or book number for the work (generally the author, with the exception of literature where it is associated with the title)

The use of a trailing X permits staff to avoid shelf-listing new works and preparation of a shelf list temporary record.

GUIDELINES:

1. WORKS NEW TO YALE WITH LC COPY OR RLG MEMBER COPY WITH LC CLASSIFICATION:

a. Use call number found on catalog copy

b. Add trailing X as the last element of the book or

Cutter number:

EXAMPLE: HV6543 H66X 1990 (LC)

c. DO NOT FILE A SHELF TEMP

2. ADDED EDITIONS:

a. Always consult Orbis first to determine call number for previous edition.*

b. Use call number established for previous edition(s), adding date of publication to distinguish editions.

If previous edition call number contains a trailing X, the added editon call number must also contain a trailing X.

If the previous edition call number does not contain a trailing X, the added edition call number must not contain a trailing X.

c. DO NOT FILE A SHELF TEMP

* Generally, it is unnecessary to consult the shelf list or other card file to determine whether Yale has other editions; however, in the case of retrospective cataloging there may be occasions when a card file may be consulted. Use judgement!

2.1.ADDED EDITIONS: SPECIAL SITUATIONS:

a. If choice of entry on LC copy has changed (i.e. author to title) accept new Cutter or book number, adding trailing X.

b. American and British editions published in the same year will use the same call number, distinguished by the addition of the letter B to the date for the added edition

c. DO NOT FILE A SHELF TEMP

3. NEW TRANSLATIONS:

a. Whenever original work has been established without trailing X, add translation cutter.

b. Do not add trailing X

c. DO FILE SHELF TEMP

d. Whenever original work has been establish with a trailing X, use that call number, adding the required translation cutter.

e. DO NOT FILE A SHELF TEMP

f. Whenever translation is received first, treatment is the same as in 1: WORKS NEW TO YALE. Place the X before translation cutter.

EXAMPLE: HV6543 H66X13 1990 (LC)

4. CALL NUMBERS LACKING FULL CLASSIFICATION (LAW)

a. Use trailing X following book or Cutter number

b. DO NOT FILE SHELF TEMP

EXAMPLE: KRM C35X 1990 (LC)

5. CALL NUMBERS WHICH CONTAIN TOPICAL SUBJECT, COUNTRY, OR OTHER SUBDIVISIONS

a. Always consult Orbis first to determine if subdivision is established. Use established subdivision from Orbis or from shelf list, otherwise use subdivision given on data base copy.

b. Use trailing X on the 3rd line of call number

c. DO NOT FILE SHELF TEMP

6. LITERATURE CALL NUMBERS ("BELLES LETTRES")

a. Literary authors whose number is already established will have the trailing X placed at the end of the title cutter
