Local Modification of LC Call Numbers at SML
(DRAFT)

Catalogers at SML routinely modify "LC call numbers," i.e. call numbers assigned by the Library of Congress (the call number is often referred to as "the 050") as well as call numbers assigned by OCLC member libraries using the Library of Congress classification schedules.

THE MOST COMMON MODIFICATIONS

OVERSIZE: ‡m Oversize and Folio

Oversize: Height: 28-39 cm; Width: 20-29 cm. Add ‡m Oversize to call numbers of oversize books at the end of the call number.

852

0

0

‚b fes ‚h QL737.C2 ‚i C37 8:1 (LC) ‚m Oversize

SML books have ‡k Folio inserted between the 852 ‡b and ‡h if they are 40 cm or more in height or 30 cm or more in width; ‡m Oversize is not added at the end of the call number for Folio sizes.

Arts Library oversize is Height 29-39 cm; Width 25-30 cm; Folio is 40 cm and over; 31 cm and over.

For more examples and other oversize related issues refer to the document SML Oversize (and Miniatures).

Historical note: SML oversize prior to 2008 also included a + either at the end of the call number or before the last Cutter. SML folio prior to 2008 was assigned an accession number under the letter representing broad LC classification, e.g. Folio N 373 (LC).

(LC) AT END OF CALL NUMBER

(LC) is added to all LC call numbers that file in the union shelf or the Kline shelf. There are some exceptions observed at SML locations.

1. SML

For (LC) notation purposes, "SML" comprises SML stacks including Judaica, Cross Campus, and the SML Reference collections, e.g. SML Reference, East Asia Library Reference, Slavic Reading Room Reference. (The smaller collections follow SML stacks to facilitate transfers to and from the main collection.). For books in these locations, DO NOT USE "(LC)" with:

• all D classes
• PA-PZ (Note that (LC) notation is used with P as a single letter)
• all Q classes

EXCEPTION: SML Near East collection does not use (LC) below any call number.

For location-specific policies on the (LC) notation, refer to SML Catalog Department Location Table.

2. School and Departmental libraries. (LC) notation is used for all LC classes. Note: formerly, Kline did not use (LC) for classes GB-GC, all Q, R, S, T. The exceptional Kline practice ceased in 2000; Kline practice is now consistent with all other school and dept. libraries.

LC 050 00 TRAILING X

LC call numbers in field 050 00 are unique and accepted as is, with some exceptions. Capital X is added after the last cutter number.

050 00 call number exceptions:

• Item is classed together locally (but not by LC)
• Fine arts call numbers (N, ND, NB, NC, NE, NX; generally not NK) where the book is about a particular artist use the local NJ18 classification
• Mathematics Library uses local classification
• Avoid use of training X for serials and multiparts

History note. Until 2007, an exception was made for folio size books which were assigned accession numbers by broad LC class. Until 2008, editions & translations were kept together.

LC Classification Numbers Not Assigned by LC

LC call numbers in field 050 _4 or OCLC 090 are non-unique and trailing X is not used. The call number is generally accepted as is with the same exceptions listed above for 050 00.

In addition, for literary (belletristic) authors using author Cutters, the author Cutter is adjusted to match either the LC author Cutter or the author Cutter previously established locally. If the author has not been assigned a Cutter by LC and is new to Orbis, it must be adjusted to fit the author sequence already in place under the class number.

OTHER MODIFICATIONS

CLASSED TOGETHER CALL NUMBERS--MULTIPLE COPIES--DATES IN CALL NUMBERS

CLASSED TOGETHER CALL NUMBERS

Classification treatment (classed together/classed separately) at a library falling under the SML umbrella may differ from classification treatment used on cataloging copy. When this happens, the cataloger is expected to follow the SML treatment for the location, even when the cataloging source is LC. (Although standard classification treatment is preferred, it is not always consistent among SML libraries or even among different collections--"locations"--within a given SML library). Situations to watch out for:

• SML classes together items in a multi-part monograph or a series when the cataloging source does not
• SML classes separately (the old Yale jargon was "classed individually") where the cataloging source classes together
• SML and the cataloging source both class together, but SML uses a call number that differs from the source's

All SML catalogers are expected to check the series authority record to verify SML treatment. Generally, a series record for any classed together analyzed series or multi-part monograph should have been created. The call number to be used (with the addition of a volume number) should have been entered in the 090 field preceded by SML (or ART, etc.). An 090 field should be created for every location holding the series or multi-part; an 090 for SML does not imply similar treatment for ART. Situations to watch out for:

• Old series is classed together, but 090 is not on the authority record. If you notice that other analytics have a volume in the call number but there is no 090 in the series authority record, bring this to the attention of your supervisor; the series authority record must be updated
• 090 appears in the series authority record but not for your location. Bring this to the attention of your supervisor; the series authority record must be updated
• New series is classed together by LC, but 090 is not on the record. If your LC 050 has a volume in the call number but there is no indication on the series authority record that a local decision has been made to follow or not follow LC, bring this to the attention of your supervisor; the series authority record must be updated

MULTIPLE COPIES

If a call number has already been assigned to an earlier copy, generally use the same number, bearing the following exceptions in mind:

1. Use the appropriate policy for "(LC)" below the call number for the location being added
2. Use the appropriate oversize policy for the location being added
3. Use LC classification if the other copy does not

DATES IN CALL NUMBERS

Background: Yale policy was to leave off the date in the call number of first editions (with certain exceptions). In 1983, LC instituted a policy of including the publication date in most of its call numbers; most research libraries followed suit. To simplify processing, current copy cataloging procedure is to accept the date in the call number assigned by the source copy if there is one. Although not required, in current practice a date is usually added to the call number if there is none. Later editions of a work always have a date in the call number.

Exceptions to accepting the source copy call number date "as is" are:

• Work letters following the date are deleted in the absence of a conflict (e.g., 1984a is modified to 1984).
  • EXCEPTION: The work letter does not have to be deleted if the source copy is 050 00. Note that letter "z" following the date indicates that the date is incomplete, e.g. [196-] in 260 is entered as 1960z in the call number. Note that if different works have the same class number & have the same corporate main entry, the same Cutter number is assigned, and the works are distinguished by date, and, if necessary, by work letter.
• CIP dates are corrected to reflect the actual publication date when there is a discrepancy
• Work letter following the date is added if a location filing in the SML Union Shelf has another edition with the same date. At SML work letters begin with B (A is reserved for photocopies) and are always capitalized
• Photocopies always have a date in the call number; the date is always followed by capital A, e.g. 1893A. The call number date of a photocopy is always the original date of publication, not the date of publication of the photocopy edition. A book originally published by Princeton University Press in 1954 and reprinted as a photocopy by University Microfilms in 1984 would have the call number date 1954A. It is no longer the practice to add photocopies to records for the original (the A was not added to the date in that situation).
• Call numbers for reprint editions (in contrast to "on-demand" photocopies issued primarily by UMI) take the date of publication (without A), not the date of the original. (Rule of thumb: for photocopies, the actual publisher is identified in the 533 field and the original publisher is identified in the 260 field; for reprint editions, the actual publisher is identified in the 260 field and the original publisher is identified in a 500 or 534 field.)
• Supplements are distinguished by numbers rather than dates. Example: .K56 1995, .K56 1995 Suppl, .K56 1995 Suppl 2 (the first Suppl came out in 1996; the second in 1997)
• If both a date of publication and a copyright date are present in the 260 field, use the date of publication in the call number
