General Guidelines

  1. With the implementation of the PCC Bibliographic Standard Record [BSR] Jan. 4, 2009, YUL cataloging revised its standard for printed books and reproductions to be consistent with PCC. As of Oct. 1, 2010, PCC extended BSR guidelines to non-print formats, and the revised YUL guidelines are intended to be compatible with the Bibco extension.
  2. Yale BSR is now the default for printed books and reproductions, cartographic materials, printed/manuscript music, sound recordings, rare materials, and video, replacing YUL Core. Because BSR is a "floor" concept, additional data may be added to a given record on a case by case basis, but, at YUL, generally not across the board. Special collections can require additional data across the board to serve the collection's needs. Follow the CONSER Standard Guidelines for continuing resources.
  3. Additional cataloging data will be added to the record at the request of users. Catalog Managment Team is expected to receive most requests via CatProblems. If CMT cannot resolve, the problem will be routed to the appropriate cataloger.
  4. If all of the access points on the Yale core record are supported by national authority records, contribute the record as a Bibco BSR (042 pcc, Cataloging Source c, Encoding Level blank [I if cataloging on OCLC]). Keep in mind that the BSR requires a 050 _4 classification number.
  5. Don't edit down: When upgrading minimal or less-than-full member, vendor, or LC copy to BSR level, you will often find that the record includes fields not required by the BSR that would be required or included in what was formerly considered to be a full record. Leave such fields in the record, provided that the information is accurate & observes standards. Apply the same principle when basing variant edition cataloging on a full level bibliographic record. Do not edit member copy to BSR level from full level.
  6. Legacy bibco cataloging copy. Generally make no attempt to upgrade a bibco cataloging copy created according to the previous standard to the new standard. MARS will update any obsolete headings. However, perform additional authority work if necessary.

Fixed Fields

When cataloging on Orbis:

Leader: Encoding Level (ElvL): 4 is the default value for YUL BSR. Retain 4 even if additional fields are added on a case-by-case basis. If variant edition cataloging is derived from a full record, leave the Encoding Level at full if the original record was Cataloging Form:a. If the Encoding Level of the original record was Cataloging Form:_ or i, use Encoding Level 1.

You must change the Encoding Level to blank or OCLC I if the record is contributed as pcc.

NOTE: a record for a reproduction derived from the record for the print original must have a Cataloging Form:a to be contributed as pcc; in other words, the source cataloging for the print original must be coded as AACR2 for the reproduction record to be contributed as pcc.

006 Not required

007 When appropriate (for microfilm, sound recordings, video, etc.). In general, only the Category of Material and SMD are required. [Previous standard required all fixed fields] Special units can define fuller requirements for their units.

008 Use Cataloging Source d. However, if all headings are backed up by authority records, the record has an 050 _4, & the description is current AACR2, use Cataloging Source c (and add 042 pcc and verify that the Encoding Level is blank or I [as in India]). Many 008 character positions are no longer mandatory, but the mandatory fields will differ based on the category of material. EXCEPTION: if the copy source is LC, leave the Cataloging Source as blank, even if you upgrade MLC to the Bibco Standard level..

When cataloging on OCLC: since the template will not recognize the fill character until the next revision of Connexion, continue to enter the appropriate 008 fixed fields.

General Requirements for Variable Fields

Variable fields. Required fields for control numbers and codes:

Tag Comment Tag Comment
010 Retain on record; add if on item 041 NEW with BSR
020 $a only is mandatory, but $a is mandatory for both the set ISBN and the individual volumes if both numbers are on the item. Note that since description is based on the earliest/first volume, only the ISBNs on that volume would be required. 042 If all headings are established, there is a 050 _4, & description follows current AACR2, make a 042 with the pcc code
035 OCLC & YL number, any additional numbers required by the cataloging unit [Local requirement] 050 _4

$a mandatory if record is coded as pcc; mandatory if used for the YUL location; recommended if not.
Classification should be at the same level of specificity used for a full record. See also CALL NUMBER


Variable fields. Required fields for description:

Tag Comment Tag Comment
245 $a, $b, $n, $p, $c. For parallel titles, transcription of the first parallel title only is mandatory. If neither the title proper nor the first parallel title is in English, any subsequent English language parallel title should be transcribed as well 500 For source of title only; additional requirements for some non-print formats
246 1_ Use cataloger judgment; not required to follow LCRIs.
NEW: use 1_ for all 246 fields except parallel title
501 Publisher bound with note
246 31 NEW: Use for parallel titles only 502 Dissertation note
250 Required if applicable 505 "Supply as appropriate for collections, compilations, or for multi-part items with separate titles." Does not extend to TOC
260 NEW: if a publisher statement has multiple locations, only the first location is recorded 533 Reproduction note. 534 is not mandatory except for cartographic materials. YUL local decision: continue to use 534 when appropriate.
546 Language note; make if language is not clear from the description; use also for alphabets, scripts, symbol systems.

YUL will continue to use $c for books [not mandatory in BSR for books].

Mandatory in BSR for non-print

$e is not mandatory for books but is mandatory for non-print. YUL: local decision--record accompanying material with books either in $e or in a note.

590 Local note. Follow AACR2 note order and enter the 590 last. Beinecke will continue to enter the 590 as the first note.
4xx Required if applicable    

CAUTION: Table above presents notes in MARC numerical order. The note order following AACR2 should be: 500, 546, 502, 505, 501, 533, 590. LC in-house practice includes 504 for bibliographical references (or combined index/bibliographical references) or 500 for index if there are no bibliographical references. YUL: cataloger judgment.

Notes to justify access (main entry or added entries) are not required for BSR. However, if a heading is not represented by an authority record, and the usage can only be documented by a note, the cataloger should either create an authority record or make a (quoted) note, so that some record of usage is recorded.

Variable fields. Required fields for access.

Tag Comment

Required if applicable

1xx/240 Required for music only. For other formats, required if applicable if the uniform title is readily available.
4xx/8xx Required if applicable. BSR only requires 4xx; YUL requires 8xx if applicable. CONSER standard does not require 4xx for serials
7xx Required if applicable. Assign the same number of added entries as you would for a full record.

6xx. If applicable, required for primary subjects. Primary subjects should be as specific as the ones that would be assigned for a full level record. Remember that some topics can only be expressed with multiple headings. If there are specific Subject Cataloging Manual (SCM) instructions to assign an array of subject headings, follow SCM. Follow documented local practices for special subject tracings. BUT: what SCM calls "LC practice" is LC's local practice and is not required, e.g. most topical subject headings for belletristic titles.

For 6xx examples see slides 17-22 in the PPT training slides for YUL BSR for books.

852 (CALL NUMBER). Classification should be at the same level of specificity used for a full record. If YUL local practice requires local classification, use local classification in 852; assign an LC class number in 050 _4 if readily available. Absent a 050, the record cannot be coded as pcc. A full call number is required for LSF.

Authority Control

Continue to follow previously established YUL guidelines for heading validation. For documentation, see

Unlike the PCC BSR, YUL BSR does not require that every heading on the bibliographic record be supported by an authority record. Continue to follow previously established YUL guidelines for when to contribute a new authority record to the national authority file. For documentation, see

Even though YUL guidelines only require authority records to be made for a limited set of conditions, in many cases all headings on a bibliographic record will be supported by a national authority record. In that case, if the record also has a 050 _4, contribute it as PCC core/Encoding Level blank.

Additional Format Specific BSR Requirements

Only differences from the general BSR guidelines are listed. Unless otherwise noted, follow the general BSR guidelines.

245-4xx. Follow DCRMB for transcription; abbreviation of the fields should be guided by DCRMB

260 [General] "DCRM(B) has careful guidelines about providing imprint and manufacturer information; following those guidelines, it would be possible to supply the full array of subfields; however, for the BSR for Rare Books, use manufacturing information only when lacking parallel publishing information. For items with only one publisher but multiple places presented, catalogers should follow DCRM(B) 4B6.2."

260 $e $f $g "Lacking substantive information for $a and/or $b, supply useful information in manufacturer subfields."

5xx In addition to the mandatory textual monograph notes, base mandatory notes on DCRM(B) "in particular situations." Note that 505 is not mandatory for Rare Books.
