MARC 21







MARC 21 

MARC (MAchine-Readable Cataloging) standards are a set of digital formats for the description of items catalogued by libraries, such as books. Working with the Library of Congress, American computer scientist Henriette Avram developed MARC in the 1960s to create records that could be read by computers and shared among libraries. By 1971, MARC formats had become the US national standard for dissemination of bibliographic data. Two years later, they became the international standard. There are several versions of MARC in use around the world, the most predominant being MARC 21, created in 1999 as a result of the harmonization of U.S. and Canadian MARC formats, and UNIMARC, widely used in Europe. The MARC 21 family of standards now includes formats for authority records, holdings records, classification schedules, and community information, in addition to the format for bibliographic records.

MARC 21 was designed to redefine the original MARC record format for the 21st century and to make it more accessible to the international community. MARC 21 has formats for the following five types of data: Bibliographic Format, Authority Format, Holdings Format, Community Format, and Classification Data Format. Currently MARC 21 has been implemented successfully by The British Library, the European Institutions and the major library institutions in the United States, and Canada.

MARC 21 is a result of the combination of the United States and Canadian MARC formats (USMARC and CAN/MARC). MARC21 is based on the NISO/ANSI standard Z39.2, which allows users of different software products to communicate with each other and to exchange data.

MARC 21 allows the use of two character sets, either MARC-8 or Unicode encoded as UTF-8. MARC-8 is based on ISO 2022 and allows the use of Hebrew, Cyrillic, Arabic, Greek, and East Asian scripts. MARC 21 in UTF-8 format allows all the languages supported by Unicode.

MARC 21 is the product of the integration of USMARC, UKMARC and CANMARC (Canadian MARC). It is the most extensively used MARC format in the world and a de facto standard. It has been designed to be both a production format and an exchange format. The current maintenance agency for MARC 21 is the Library of Congress. There are five MARC 21 formats: 
  • Bibliographic
  • Authorities
  • Holdings
  • Classification
  • Community information
The future of the MARC formats is a matter of some debate among libraries. On the one hand, the storage formats are quite complex and are based on outdated technology. On the other, there is no alternative bibliographic format with an equivalent degree of granularity. The billions of MARC records in tens of thousands of individual libraries (including over 50,000,000 belonging to the OCLC consortium alone) create inertia. The Library of Congress has launched the Bibliographic Framework Initiative (BIBFRAME), which aims at providing a replacement for MARC that provides greater granularity and easier re-use of the data expressed in multiple catalogs.

Note: This article is Under Development.

MARC 21 FORMAT FOR BIBLIOGRAPHIC DATA




A MARC record is composed of three elements: the record structure, the content designation, and the data content of the record. The record structure is an implementation of the international standard Format for Information Exchange (ISO 2709) and its American counterpart, Bibliographic Information Interchange (ANSI/NISO Z39.2). The content designation--the codes and conventions established explicitly to identify and further characterize the data elements within a record and to support the manipulation of that data--is defined by each of the MARC formats. The content of the data elements that comprise a MARC record is usually defined by standards outside the formats. Examples are the International Standard Bibliographic Description (ISBD), Anglo-American Cataloguing Rules, Library of Congress Subject Headings (LCSH), or other cataloging rules, subject thesauri, and classification schedules used by the organization that creates a record. The content of certain coded data elements is defined in the MARC formats (e.g., the Leader, field 007, field 008).

Scope of the Bibliographic Format

MARC 21 Format for Bibliographic Data is designed to be a carrier for bibliographic information about printed and manuscript textual materials, computer files, maps, music, continuing resources, visual materials, and mixed materials. Bibliographic data commonly includes titles, names, subjects, notes, publication data, and information about the physical description of an item. The bibliographic format contains data elements for the following types of material:


  • Books (BK) - used for printed, electronic, manuscript, and microform textual material that is monographic in nature.
  • Continuing resources (CR) - used for printed, electronic, manuscript, and microform textual material that is issued in parts with a recurring pattern of publication (e.g., periodicals, newspapers, yearbooks). (NOTE: Prior to 2002, Continuing resources (CR) were referred to as Serials (SE)).
  • Computer files (CF) - used for computer software, numeric data, computer-oriented multimedia, online systems or services. Other classes of electronic resources are coded for their most significant aspect. Material may be monographic or serial in nature.
  • Maps (MP) - used for all types of printed, electronic, manuscript, and microform cartographic materials, including atlases, sheet maps, and globes. Material may be monographic or serial in nature.
  • Music (MU) - used for printed, electronic, manuscript, and microform music, as well as musical sound recordings, and non-musical sound recordings. Material may be monographic or serial in nature.
  • Visual materials (VM) - used for projected media, non-projected media, two-dimensional graphics, three-dimensional artifacts or naturally occurring objects, and kits. Material may be monographic or serial in nature.
  • Mixed materials (MX) - used primarily for archival and manuscript collections of a mixture of forms of material. Material may be monographic or serial in nature. (NOTE: Prior to 1994, Mixed materials (MX) were referred to as Archival and manuscript material (AM)).


Kinds of Bibliographic Records

MARC bibliographic records are distinguished from all other types of MARC records by specific codes in Leader/06 (Type of record) which identifies the following bibliographic record types.
  • Language material
  • Nonmusical sound recording
  • Manuscript language material
  • Musical sound recording
  • Computer file
  • Projected medium
  • Cartographic material
  • Two-dimensional nonprojectable graphic
  • Manuscript cartographic material
  • Three-dimensional artifact or natural objects
  • Notated music Kit
  • Manuscript music
  • Mixed material

Components of Bibliographic Records

Description of Record Parts

A MARC bibliographic record consists of three main components: the Leader, the Directory, and the variable fields. The following information summarizes the structure of a separate MARC record. More detail is provided in MARC 21 Specifications for Record Structure, Character Sets, and Exchange Media.
  • Leader - Data elements that primarily provide information for the processing of the record. The data elements contain numbers or coded values and are identified by relative character position. The Leader is fixed in length at 24 character positions and is the first field of a MARC record.
  • Directory - A series of entries that contain the tag, length, and starting location of each variable field within a record. Each entry is 12 character positions in length. Directory entries for variable control fields appear first, sequenced by the field tag in increasing numerical order. Entries for variable data fields follow, arranged in ascending order according to the first character of the tag. The stored sequence of the variable data fields in a record does not necessarily correspond to the order of the corresponding Directory entries. Duplicate tags are distinguished only by the location of the respective fields within the record. The Directory ends with a field terminator character (ASCII 1E hex).
  • Variable fields - The data in a MARC bibliographic record is organized into variable fields, each identified by a three-character numeric tag that is stored in the Directory entry for the field. Each field ends with a field terminator character. The last variable field in a record ends with both a field terminator and a record terminator (ASCII 1D hex). There are two types of variable fields.
  • Variable control fields - The 00X fields. These fields are identified by a field tag in the Directory but they contain neither indicator positions nor subfield codes. The variable control fields are structurally different from the variable data fields. They may contain either a single data element or a series of fixed-length data elements identified by relative character position.
  • Variable data fields - The remaining variable fields defined in the format. In addition to being identified by a field tag in the Directory, variable data fields contain two indicator positions stored at the beginning of each field and a two-character subfield code preceding each data element within the field.
  • The variable data fields are grouped into blocks according to the first character of the tag, which with some exceptions identifies the function of the data within the record. The type of information in the field is identified by the remainder of the tag.

Following describe the intellectual and physical characteristics of bibliographic resources (books, sound recordings, video recordings, and so forth).

GUIDELINES FOR APPLYING CONTENT DESIGNATORS

Content designators identify the subelements occurring in a name or name/title heading that contains a personal name constructed according to generally accepted cataloging and thesaurus-building rules (e.g., Anglo-American Cataloguing Rules (AACR2), Library of Congress Subject Headings (LCSH)). Personal names used in phrase subject headings (e.g., John, the Baptist, Saint, in the Koran) are contained in the X50 fields.

Only generally-applicable content designators are described in full in this section. A small number of content designators with field-specific instructions are described in the Tracings and References-General Information section (for field 400 and 500) and the 7XX Heading Linking Entries-General Information section (for field 700).

 INDICATORS

First Indicator - Type of personal name entry element

Form of the entry element of the name portion of a heading. The values distinguish among forenames, surnames, and family names used as the entry element.

0 - Forename

Forename or a name consisting of words, phrases, initials, separate letters, or numerals that are formatted in direct order.

1 - Surname

Surname formatted in inverted order (surname, forename) or a name without forename(s) which is known to be a surname. If there is uncertainty that a name without forename(s) is a surname, the first indicator position contains value 0. Phrases, when formulated with inversion and an entry element similar to a surname are treated as a surname.

Second Indicator

In fields 100400, and 500, the second indicator position is undefined and contains a blank (#). For field 700, the second indicator position contains one of the values described in the 7XX Heading Linking Entries-General Information section.

 SUBFIELD CODES

$a - Personal name

Name may be a surname and/or forename; letters, initials, abbreviations, phrases, or numbers used in place of a name; or a family name. A parenthetical qualifying term associated with the name is contained in subfield $c, and a fuller form of name added as a qualifier is contained in subfield $q.

$c - Titles and other words associated with a name

Includes qualifying information such as

  • titles designating rank, office, or nobility, e.g., Sir
  • terms of address, e.g., Mrs.
  • initials of an academic degree or denoting membership in an organization, e.g., F.L.A.
  • a roman numeral used with a surname
  • other words or phrases associated with the name, e.g., clockmaker, Saint.

If the entry element is a surname followed directly by a prefix without intervening forenames or forename initials, the prefix is contained in subfield $c to prevent its being treated as a forename in searching and sorting processes.

4001#$aSanctis,$cDe

Multiple adjacent titles or words associated with a name are contained in a single subfield $c. Subfield $c is repeated only when words associated with a name are separated by subelements contained in other subfields.

Subject: [SACOLIST] Announcement: New coding in proposals
To: <SACOLIST@listserv.loc.gov>



Hello SACO members,

This message details new coding that catalogers in SACO institutions are to use when making proposals for subject headings, genre/form terms, and medium of performance terms. These new instructions support LC’s linked data efforts, and are effective immediately.

According to longstanding policy, field 670 subfield $a contains the LC bibliographic record control number (i.e., the LCCN) if applicable, the main entry, the title, and the publication date of the work. 

The LCCN will now be coded in subfield $w, which will be the final element of the field. The LCCN is preceded by LC’s MARC organization code, DLC, enclosed in parentheses. Example:

            Citation formatted according to former policy:
670 ## $a Work cat: 2015300502: Finding Julia, 2014: $b p. 13 (Bollinger family) p. 11 (Bollinger County, Missouri was named after George Frederick Bollinger, b. 1770. His German ancestors migrated from Zurich, Switzerland to Philadelphia in 1738)

            Citation formatted according to new policy:
670 ## $a Work cat: Finding Julia, 2014: $b p. 13 (Bollinger family) p. 11 (Bollinger County, Missouri was named after George Frederick Bollinger, b. 1770. His German ancestors migrated from Zurich, Switzerland to Philadelphia in 1738) $w (DLC)2015300502

Catalogers in SACO institutions must provide the LCCN in 670 subfield $w when the proposal is made for a CIP cataloged in LC’s CIP Partnership Program.

“Work cat” citations in other SACO proposals may contain a single subfield $w that reflects either the local control number of the SACO institution or a bibliographic utility control number (e.g., the OCLC number). If provided, the number should be preceded by the MARC organizational code to which the control number applies (e.g., $w (OCoLC)236328585). Subfield $w is not required for SACO proposals, other than for those proposals made to support CIP cataloging.

Catalogers making a proposal to revise an existing record should code the new “Work cat.” citation in the new way, but should not revise the existing citations. Do not revise citations in existing authority records to move to subfield $w an LCCN that appears in subfield $a, nor to add a control number to a citation that does not currently include a control number.

The new coding is required only in “Work cat.” citations, not in citations for reference sources. The new policy affects only proposals for subject headings, genre/form terms, and medium of performance terms. It does not impact name authority records.

Beginning September 1, PTCP will return miscoded proposals to catalogers for correction before the proposal will be scheduled for a list.

The new policy on 670 subfield $w is documented in Subject Headings Manual (SHM) H 200 sec. 9.a., and the templates in the Proposal System have been updated to remind catalogers to use the new subfield.
