1. Background on CONSER Record Requirements

1.1. Reevaluation of CONSER Record Requirements

At the end of 1992, the CONSER Policy Committee charged the Core Elements Task Force to evaluate the nature of the CONSER record; to determine the core elements of the record, with an emphasis on the identification of the publication; and to reevaluate the bibliographic requirements for CONSER cataloging. In Spring 1993, the CONSER Operations Committee endorsed this review of the bibliographic requirements.

In late 1993, the Cooperative Cataloging Council (CCC) defined a core level record for monographs to serve as an intermediate level between full- and minimal-level records. While the CCC has undertaken supplementary initiatives to define core record standards for other types of material (e.g., JACKPHY, Music) it left the definition of such a standard for serials to CONSER. In February 1994, the CONSER At-Large group indicated its interest in exploring the utility of a core record for serials and the Core Elements Task Force was asked to draft the CONSER "Core Record for Serials" proposal.

In 1994 the CONSER Policy and Operations committees considered the proposal for a "Core Record for Serials" at their annual meetings. The committees endorsed retaining modified versions of minimal- and full-level records and establishing a third core-level record for CONSER.

These new requirements support several of the goals listed in the CONSER Plan: CONSER members are committed to creating and maintaining high-quality, authoritative records for serials; providing identification, bibliographic description and access, and subject analysis; without limitation to subject, language, script, format, or source. CONSER recognizes the need for individual members to retain flexibility in determining the level of fullness needed in describing collections and titles understanding that, ideally, the fuller the information, the more useful it is for others.

1.2. Change in the Listing and Description of CONSER Record Requirements

The previous edition of the CONSER Editing Guide included record requirement codes in tables at the beginning of each field listed in Part II. Additional explanations of requirements for specific fields were indicated in the description of the field. The preparation of the 1994 edition coincided with the reevaluation of CONSER record requirements and Program members decided not to have codes listed in tables as before. This section on record requirements, including lists of fields, replaces the tabular indications of record requirements previously followed by CONSER catalogers. Where more specific details concerning requirements are needed, these are incorporated into the text of the field. Record requirements for non-print serials will be included in Appendix N, once defined.

2. Description of Record Levels

The levels of CONSER records are characterized briefly as follows:
  • Full level records contain a full complement of elements that are applicable to the serial and all elements contained are fully authoritative.
  • Core level records contain those elements essential to the description and access of the serial and all elements contained are fully authoritative.
  • Minimal level records contain the essential (i.e., core) elements for description but subject elements may not be present and one or more headings may not be authoritative.

Specific details concerning the description, subject elements, and authoritativeness of headings are given below. Classification, however, is not required at any level, with one exception: field 086, Government Document Classification Number, is input as supplied by the U.S. Government Printing Office. Many libraries do not classify a portion of their serial collection and a number of different classification schemes are used.

Computer-generated fields are also part of all CONSER records but are not specifically stated here because there is no conscious decision to include or exclude them. These fields are specifically labeled in Part II. Fields 012 (subfield i) and 850 have been included for all levels of CONSER records (except newspapers) because they are needed to generate entries in the publication New Serial Titles. These fields are only needed for first time authentication, however, and CONSER institutions who later use the record are not required to add their holdings to field 850. For more information, see fields 012 and 850 in Part II.

2.1. Full record elements

  • Description: Descriptive elements coded above "as M or MA for full level and appropriate per AACR 2 and the Library of Congress Rule Interpretations (LCRIs) are included in the record.
  • Name/series headings: Name/series headings are checked in the authority file. If the name/series is established, the authorized form is used. If it is not established, an authority record is created and added to the authority file.1 Field 042 is coded as "lcd."
  • Subject headings: All appropriate subject headings are included in new records, according to the relevant standard. Subject headings found in non-CONSER records are checked for current validity and appropriateness. Construction and tagging are also checked to conform with the existing standard.
  • Classification: Classification is not required but is encouraged in full-level records.

2.2. Core record elements

  • Description: Descriptive data elements coded above as M or MA for core records are included as appropriate per AACR2 and the LCRIs.
  • Name/series headings: Name and series headings are checked in the authority file. If the name or series is established, the authorized form is used. If it is not established, an authority record is created and added to the authority file.1 Field 042 is coded as "lcd."
  • Subject headings: In new records, only subject headings most essential to the identification/access of the serial are supplied. In adapted records, subject headings are checked for current validity and appropriateness; construction and tagging are also checked.
  • Classification: Classification is not required.

Core record requirements are intentionally flexible to allow for local interpretation and rely heavily on cataloger's judgment. Cataloger's judgment is based on a knowledge of serials, the cataloging rules and interpretations, and the needs of one's institution. For example, notes are given in core records if the information is "essential" to adequately identify the serial and/or its relationships, or to clarify access points. What is "essential" is left to the cataloger to determine. Name and title added entries are also required if they are essential for record access or to adequately identify the serial or its relationships.2

A certain amount of local interpretation or cataloger judgment may also be in order when determining the extent of subject headings generally assigned in a core record. The core level states that only subject headings most essential to the identification/access of the serial are supplied. It is up to the cataloger to decide what is "most essential." A general principle to be followed is that once a field is determined to be appropriate for the serial, the contents are given according to AACR2 and the LCRIs or a standard thesaurus in the case of subject elements. Catalogers cannot arbitrarily choose to ignore rules or leave out information because they are creating core records. In this way, other catalogers wishing to upgrade the record to "full" can add additional data without having to reevaluate the data already present in the record.

2.3. Minimal record elements

  • Description: Descriptive elements that are coded above as M or MA for "minimal" are included as appropriate per AACR2 and the LCRIs.
  • Name/series headings: Name headings are checked in the NAF. If present, the authorized heading is used. If not present, the heading is constructed according to AACR2, but an authority record need not be submitted to the NAF. Series headings are checked in the NAF. If present, the authorized heading is used. If not present, the series is coded as 490 0 (series not traced). Field 042 is coded as "lcd" or "msc," as appropriate (see field 042).
  • Subject headings: Subject headings are not required in new records. In adapted records, subject headings may be left as found.
  • Classification: Classification is not required.

The primary difference between core and minimal is that name authority work and subject analysis are not required. The same principle that applies to core records also applies to minimal, that once a field is determined to be applicable, the contents are given according to AACR2 and the LCRIs.

3. Maintaining and Upgrading Three Levels of CONSER Records

3.1. Maintaining CONSER records

Maintaining records involves updating the record when changes have occurred to the serial, the cataloging rules/interpretations, or the USMARC format.

Maintenance of records assures that elements contained in the records are up-to-date, as instructed in B4. If elements are added to records in the process of routine maintenance, this does not generally constitute an upgrading of the record.

3.2. Upgrading CONSER records

Upgrading CONSER records involves reassessing the record to determine whether additional notes, added entries, links, subject headings, or coded fields are applicable that would have been added if the record were originally cataloged at the higher level. It may also require that headings be made authoritative.

Minimal level records may be upgraded to core or full level; core level records may be upgraded to full level. A minimal level record that is upgraded to core will likely require the addition of subject elements and/or the addition of names to the Name Authority File. A core record that is upgraded to the full level might require additional name or subject added entries, notes, links, or coded fields.

Upgrading the record involves a change in encoding level. If a minimal record is upgraded to full or core, the encoding level is changed from "7" to "blank" or "4," as appropriate.

3.3. First-time Authentication of Non-CONSER Records

CONSER catalogers should keep in mind that the core record was introduced primarily as a time-savings for the creation of new records. Existing non-CONSER records that are to be authenticated for the first time will be found in OCLC coded as full (I) or minimal (K). If a quick perusal of the record indicates that a record coded as full is really minimal or core and you are not upgrading the level, you may assign the appropriate USMARC code for that level in the Encoding level. For the most part, however, accept the level as found. If you had planned to do core cataloging for an item and a record is found at the full level, keep it as such. Do not spend time trying to determine whether it really is full or not! Also, do not go back and recode CONSER records created before the definition of a core record.

4. CONSER Core Record Requirements for Serials in Special Formats -- Microforms, Newspapers, Computer Files, Music, Sound Recordings, Visual Materials, Cartographic Materials

Record requirements for serials in special formats differ slightly from those for serials in print format because some fields not applicable to standard print publications are considered essential for non-print formats. To address record requirements for the wide range of serials in special formats, CONSER has developed this series of core records for serial microforms, newspapers, computer files, music, sound recordings, visual materials, and cartographic materials. (For more information on additional elements for non-print serials and sample records, refer to Appendix N, "Special Physical Formats.")

Section B6.2.2, "Core Record Elements," includes the general description and nature of the core record that is consistent for all serial formats. CONSER policies on authority requirements, name/series and subject headings, and classification for the standard core record also apply to each of the non-print core records. Core requirements for special formats have been developed in consultation with core record task groups operating under the Program for Cooperative Cataloging (PCC), and other experts in the field.

In general, a select number of fields that are considered essential for the special format have been added to the standard CONSER core record to obtain the core record for the special format. In a few cases a core element for the standard print serial is not included simply because the field would not be applicable to serials in the special format (e.g., field 240, uniform title, for newspapers). These core records represent field-level requirements; however, certain elements at the subfield level, such as the 245 $h (GMD) may also be required. Specific instructions on the application of non-print fields are included with the description of each field in Part II and in Appendix N.

Requirements for multi-format serials, such as newspapers on microform or computer file maps, are not specifically addressed here. It is generally expected that the core elements unique to each special format will be added to the standard core record to obtain the multi-format serial core record. Core elements that are distinctively characteristic to the special format are discussed below and identified by a footnote next to the requirement code in the tables. (See "Fixed Length Fields--General Information" in Section E for information on inputting records for multi-format serials and their fixed fields.)

4.1. Core record for microforms

In addition to the standard CONSER core elements, four fields have been added to the core record for microforms: 007, Physical description fixed field; 300, Physical description; 533, Reproduction note, and; 776, Additional physical form entry. Of these, only field 007 is applicable to all microforms and is mandatory for serial microforms. Field 300 is required for original microforms while field 533 is required for microform reproductions. For preservation master microform reproductions, field 776 is mandatory in the microform record and the record for the original when both are present in the OCLC online catalog. Refer to Part II, field 776, for additional guidelines for the field. CONSER uses the general material designation (GMD, 245 $h) "microform" for all such records.

4.2. Core record for newspapers

The CONSER core record for newspapers includes three fields not included in the standard core record: 310, Current publication frequency; 752, Added entry -- Hierarchical place name, and; 775, Other edition available entry. The frequency for a newspaper is often an essential identifying element, the place name added entry is considered an essential access point for newspapers, and related editions are also bibliographically significant. A number of standard core elements are not applicable to newspapers and are not included in the newspaper core record: 074, GPO item number; 086, Government document classification number; 240, Uniform title; 4XX, Series statement, and; 8XX, Series added entries.

4.3. Core records for computer files

Two separate computer file core records are listed here to emphasize the elements required for each: one for direct access computer files (e.g., CD-ROMs), and another for remote access computer files (e.g., Internet resources). Two non-print fixed field elements are considered essential and included for all computer file serials: Type of computer file (008/26) and the 007 Physical description fixed field. Field 538, System details note, is mandatory for all computer files. Records for direct access computer files require the field for the system requirements note while remote access computer files use the field for the mode of access note. The only other differences with the standard core record is the addition of field 300, Physical description, for direct access computer files, and field 856, Electronic location and access, for remote access computer files. For online serials, at least one 856 field is core, and thereby considered mandatory, representing each standard Internet access scheme through which the item is found. Location and access information should be provided for the entire publication. CONSER uses the GMD (245 $h) "computer file" for all such records.

CONSER guidelines on cataloging remote access versions of printed serials. "Remote access," or "online" versions include both digital reproductions of printed serials as well as electronic versions of current issues. CONSER members are encouraged to create separate records for remote access versions, and many are doing so. However, CONSER members may optionally note the existence and identify the location of the online version on the record for the printed serial, without separately cataloging the remote access version. CONSER members will additionally provide the note and electronic location on the record for the printed serial, when separate records are created, in order to faciliate a "one-record" approach for others. This is an interim experimental policy that will be reexamined, and possibly revised, in the near future. For further details, see CONSER Editing Guide, Appendix N.

4.4. Core record for sound recordings

The following non-print elements were added to the standard core record to form the CONSER core record for sound recordings: Literary text for sound recordings (008/30-31); 300, Physical description, and; 500, Compact disc note. The Literary text for sound recordings fixed field element is considered essential for non-musical sound recordings since it identifies the nature of the work (e.g., conference proceedings, fiction, instruction). Field 300 specifies whether the title consists of sound cassettes, sound discs, etc., and other physical details. A 500 note is included for compact disc sound recordings to clarify the type of sound disc described. CONSER uses the GMD (245 $h) "sound recording" for all such records.

4.5. Core record for music

The following non-print elements were added to the standard core record to form the CONSER core record for music: 041, Language code; 300, Physical description, and; 546, Language note. The 041 field is a core requirement for translations and multilingual items (subfields $a and $h only). Considered to be essential elements are language codes for serially issued vocal music in more than one language, and language code(s) for the original language when describing translations. Field 300 for music materials generally identifies the type of scores or parts issued. The language note, field 546, is required for vocal music if the information is not evident in the body of the record.

4.7. Core record for cartographic materials

The following non-print elements were added to the standard core record to form the CONSER core record for cartographic materials: Relief (008/18-21); Type of cartographic material (008/25); Index (008/31); 034, Coded cartographic mathematical data (scale and projection information only); 255, Cartographic mathematical data (subfields $a and $b only), and; 300, Physical description.

The Relief fixed field code is usually derived from a 500 note which indicates relief forms commonly found on maps. The fixed field element is required if the information is readily available. The Type of cartographic material fixed field code indicates whether the publication is a map series, map serial, or atlas. (The Library of Congress processes map series as collected set monographs). The Index code indicates whether the item includes a location index or gazetteer. Field 034 is required if available and reflects the information found in the 255 field (coordinate subfields are not required). Field 255 contains mathematical data associated with map materials, although only the scale and projection statements are required in the core record (subfields $a and $b). The 300 field indicates whether the record represents atlases, maps, or other cartographic items.
