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 RLIN and OCLC member libraries using the Library of Congress classification schedules.

THE MOST COMMON MODIFICATIONS

OVERSIZE: ‡m Oversize and Folio

$m Oversize is added 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 40 cm. or more in height or 30 cm. or more in width are not fully classified.

For details on oversize (including Folio processing) refer to the Oversize page.

(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 (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.

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.

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. LC call numbers in field 050 _4, RLIN Holdings, or OCLC 090 are non-unique and trailing X is not used; they must be shelflisted.

050 00 call number exceptions:

• Folio size books at SML only
• Item is classed together locally (but not by LC)
• Earlier edition has a different call number (see below Keeping Editions Together)
• 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

CUTTER ADJUSTMENTS-- CLASSED TOGETHER CALL NUMBERS-- KEEPING EDITIONS TOGETHER-- DATES IN CALL NUMBERS

CUTTER ADJUSTMENTS

Cutters on LC call numbers of member libraries are adjusted to ensure the call number's uniqueness, to keep books by and about literary authors together, and to keep books shelved in alphabetical sequence within each class.

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

KEEPING EDITIONS TOGETHER (IN THE SML UNION SHELF)

Unless otherwise noted, the instructions apply to classed separately monographs (including multiparts that are not part of classed together series).

All copies of the same edition in the same location are expected to have the same call number.

Copies of the same edition in different locations (if the location files to the SML Union Shelf) are expected to have the same call number, but there are some exceptions:

• Art oversize differs from SML; absence or presence of + may be significant
• Absence of (LC) notation for certain class numbers in [SML and Kline LINK] where (LC) notation is used in school and departmental libraries
• SML Folio numbers are not used by any other location (watch out when transferring Folios from CCL to SML stacks and vice versa!)
• Variation in classed together/classed separately treatment among different locations.

Copies of the same edition in different locations are not expected to be consistent if one of the locations does not file in the SML Union Shelf. The non-Union Shelf locations are:

• Beinecke Library (but Beinecke Reference files in the SML Union Shelf)
• British Art Library Rare (British Art Reference files in the SML Union Shelf)
• Divinity Library
• Economic Growth Library
• Law Library
• Music Library
• Mathematics Library
• Medical Library
• Locations using Old Yale classification numbers (SML,Y; MUDD; SML,YAL)

Multiple copy examples:

Cataloging source classes the book in PA. First copy is for Classics, second copy is for Cross Campus. Both file in the SML Union Shelf, so both copies should have the same call number. But Classics has "(LC)" under all call numbers, while Cross Campus uses "(LC)" only for certain classes: Classics number must have (LC) below it; Cross Campus call number does not have (LC).

First copy in Art, second copy in Cross Campus. Book is 23 cm. wide. Both file in the SML Union Shelf, so both copies have the same call number. Art oversize width is 25 cm.; Cross Campus oversize width is 20 cm. CCL call number has + at the end of the call number.

Cataloging source classes in ML. First copy is in the Drama Library, second copy is in the Music Library, third copy is in Cross Campus. Drama and Cross Campus should have the same call number, since they both file in the Union Shelf. Music does not file in the Union Shelf, so it does not have the same call number.

First copy is in Medical, original cataloging done at the Medical Library. Copy Cataloger receives the 2nd copy for SML to add. The usual routine is to check the LC Resource File for an 050 call number; if a record with a number is found, the 050 number is used with trailing X. If no record is found and Medical used LC classification, the copy cataloger shelflists as if it were a call number assigned by an RLIN or OCLC library. If Medical did not use LC classification, the number is assigned by a librarian cataloger at SML.

Keeping works together

In general, works for locations filing into the SML Union Shelf are kept together by using the same call number, with the editions differentiated by the date of the edition or by the date and a work letter if 2 different editions have the same date (e.g. 1996B). No consistency is expected with editions held at locations that do not file in the SML Union Shelf. Here is a list of typical situations:

• Cutter or even the class number changes with later editions. The copy cataloger is expected to use the same cutter and class number for later editions and add the year of publication to the call number to differentiate. However, if the earlier edition uses Old Yale classification, the copy cataloger is expected to use the LC call number of the source copy; in the absence of an LC call number, an LC call number should be assigned by an original cataloger.
• If the earlier edition was assigned an LC call number by an original cataloger or other non LC source, and the later edition is cataloged by LC, the call number of the earlier edition is used
• If the call number does not change, but the size changes from oversize to regular or vice versa, the copy cataloger should delete or add + as appropriate; editions kept together in the shelflist are not necessarily kept together in terms of physical location
• Don't confuse different books with different editions. A book may be by the same author and on the same topic without necessarily being a different edition. For example, Psychoanalysis and feminism and Psychoanalysis: essays and reviews are both by Judith Mills, and may have the same class number. But the latter title is not a revised or variant edition of the earlier title, so the main entry cutter must not be the same

In general, the policy applies also to translations and the original work. If a translation is received for cataloging and SML has already cataloged the original, the translation will be assigned the same call number as the original with the addition of the appropriate translation digits. Conversely, if the original is received for cataloging and SML has already cataloged a translation, the original will be assigned the same call number as the translation minus the translation digits. Instructions for use of translation digits are on the Cataloging at Yale Tools and Resources page at:

http://www.library.yale.edu/cataloging/translation.htm

Keeping different editions together: some examples:

The only copy on Orbis up to this point is the first edition; it is in the Old Yale classification. The 2nd edition is received for cataloging for SML stacks. Procedure: 050: use trailing X. Member: accept classification but adjust cutter to maintain consistency in the shelf.

The only copy in Orbis up to this point is the first edition, which is in the Mathematics Library. The 2nd edition is received for cataloging for Cross Campus Library. Procedure: 050: as is with trailing X. Member: adjust cutter if necessary.

There are 2 copies in Orbis of the 3rd edition; one is in Medical and the other is in Engineering. The 4th edition is received for cataloging for SML stacks; because Engineering files in the SML Union Shelf, the Engineering call number is used with the date of publication of the 4th edition.

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: 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.
• 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
