The revision in 1997 of the definition for code "m" (Computer file) in Leader/06 (Type of record), that narrowed its use to a computer file content orientation, as well as the proliferation of electronic resources has prompted users to request additional guidance when coding these materials. This document presents some guidelines for coding Leader/06 in bibliographic records for electronic resources and includes examples with coding. Please note that this document discusses content designation (MARC coding and tagging); it is not a guide to cataloging rules and conventions used to create the content of bibliographic records for electronic resources.
The list of examples in this document is an ongoing work in progress. Users who encounter types of electronic resources not included in the list are encouraged to bring them to the attention of the Network Development and MARC Standards Office at the Library of Congress ([email protected]).
This document supersedes an earlier edition of these guidelines.
MARC 21 Format for Bibliographic Data: Including Guidelines for Content Designation defines the codes and conventions that identify data elements in MARC bibliographic records. It is updated on an annual regular basis.
OCLC's Cataloging Electronic Resources: OCLC-MARC Coding Guidelines assists catalogers creating bibliographic records for electronic resources and includes information on the proper coding of fixed fields, including Leader/06 (Type of record).
Guidelines for Distinguishing Cartographic Materials on Computer File Carriers from other Materials on Computer File Carriers (January 1998, revised December 2001) helps catalogers working with cartographic electronic resources to distinguish them from other types of electronic resources and to select the correct Leader/06 (Type of record) based on that distinction.
Relationship of Fields 006, 007, and 008 explains the general model adopted to indicate how repetitions of field 006 ( Fixed-length data elements - Additional material characteristics) and a single field 008 (Fixed-length data elements - General information) coexist in bibliographic records, especially in relation to the values in Leader character positions 06 (Type of record) and 07 (Bibliographic level), and clarifies the relationship of field 007 (Physical description fixed field) to fields 006 and 008.
An electronic resource is a manifestation of a work that requires the use of a computer for access. Peripheral devices attached to the computer (such as a CD-ROM drive) may also be required. The manifestation's carrier is accessed either directly (e.g., via CD-ROM, etc.) or remotely (e.g., via the Internet). Items that do not require the use of a computer, such as audio CDs or movies on DVD-videodiscs, are excluded from this definition.
The Leader/06 (Type of record) character position in the MARC 21 Format for Bibliographic Data contains a one-character alphabetic code that differentiates MARC records created for various types of content and materials. The definition of code "m" (computer file) in Leader/06 was revised in June 1997 as a result of Proposal No. 97-3R. The new definition narrowed the choice of code "m" to the following types of electronic resources:
Code "m" is defined as follows in the MARC 21 Format for Bibliographic Data:
This revised definition stipulates that catalogers code electronic resources for the significant aspects of their content, as opposed to their carrier.
The Leader/06 determines which 008 code (Fixed-length data elements - General information) is used and the appropriateness and validity of other fixed data elements in a record.
The 008 field contains character positions that provide coded information about the record as a whole and about special bibliographic aspects of the item cataloged. This field is not repeatable. Field 006 (Fixed-length data elements - Additional material characteristics) permits coding for additional aspects of an electronic resource (including any computer file aspects) if the 007 and 008 fields do not adequately describe it. Some cataloging utilities and groups (such as CONSER) require the use of 006 fields under certain conditions. Sample records in this document include 006 fields for those who may wish to use this field.
Coding all of these positions involves making a series of decisions. Consider the following when deciding what code values to select:
Leader/06 values
Leader/06 definitions
Definitions of data elements in 008/26 and 006/09 positions
for Computer files
Notes:
1) The sample records are partial records.
2) The 008/26 and 006/09 values in the columns are for Computer Files (CF)
and Electronic resources (ER).
3) Some of the records have a Leader/07 with a value of "i" (for integrating
resource). At this time, value "i" has not been widely implemented.
However, many web sites are considered integrating resources, so some of the
sample records do have a Leader/07 with this value.
4) Some of the 006 fields in the sample records do not really provide much additional
information to the records but were added for illustrative purposes.

The record describes collections of bibliographic records retrieved via search software; the presence of such software does not change the content of the resource and does not mean that Leader/06 should be coded m. The resource is primarily textual bibliographic data, so it is coded as language material. The type of computer file (006/09) is bibliographic data.

The Leader/06 (Type of record) character position contains a one-character alphabetic code that is used to differentiate MARC records created for various types of content and material.
Computer files are identified by a distinctive Type of record code only if they belong to certain categories of electronic resources as specified below; in all other cases the type of content characteristics described by other codes take precedence over the computer file characteristics of the item.
a - Language material Code a indicates that the content of the record is for non-manuscript language material. Code a is also used for microforms and electronic resources that are basically textual in nature, whether they are reproductions from print or originally produced. Manuscript language material uses code t.
c - Notated music Code c indicates that the content of the record is for printed, microform, or electronic notated music.
d - Manuscript notated music Code d indicates that the content of the record is for manuscript notated music or a microform of manuscript music.
e - Cartographic material Code e indicates that the content of the record is for non-manuscript cartographic material or a microform of non-manuscript cartographic material. This code is used for maps, atlases, globes, digital maps, and other cartographic items.
f - Manuscript cartographic material Code f indicates that the content of the record is for manuscript cartographic material or a microform of manuscript cartographic material.
g - Projected medium Code g indicates that the content of the record is for a motion picture, videorecording (including digital video), filmstrip, slide, or transparency. All of these media are intended for projection. Material specifically designed for overhead projection is also included in this type of record category.
i - Nonmusical sound recording Code i indicates that the content of the record is for a recording of nonmusical sounds (e.g., speech).
j - Musical sound recording Code j indicates that the content of the record is for a musical sound recording.
k - Two-dimensional nonprojectable graphic Code k indicates that the content of the record is for a two-dimensional nonprojectable graphic such as, activity cards, charts, collages, computer graphics, digital pictures, drawings, duplication masters, flash cards, paintings, photo CDs, photonegatives, photoprints, pictures, postcards, posters, prints, spirit masters, study prints, technical drawings, transparency masters, and reproductions of any of these.
m - Computer file Code m indicates that the content of the record is for the following classes of electronic resources: computer software (including programs, games, fonts), numeric data, computer-oriented multimedia, online systems or services. For these classes of materials, if there is a significant aspect that causes it to fall into another Leader/06 category, code for that significant aspect (e.g., vector data that is cartographic is not coded as numeric but as cartographic). Other classes of electronic resources are coded for their most significant aspect (e.g. language material, graphic, cartographic material, sound, music, moving image). In case of doubt or if the most significant aspect cannot be determined, consider the item a computer file.
o - Kit Code o indicates that the content of the record is for a mixture of various components issued as a unit and intended primarily for instructional purposes. No one component is identifiable as the predominant component of the item. Examples are packages of assorted materials, such as a set of school social studies curriculum material (books, workbooks, guides, activities, etc.), or packages of educational test materials (tests, answer sheets, scoring guides, score charts, interpretative manuals, etc.).
p - Mixed materials Code p indicates that there are significant materials in two or more forms that are usually related by virtue of their having been accumulated by or about a person or body. The intended primary purpose is other than for instructional purposes (i.e., other than the purpose of those materials coded as o (Kit)). This category includes archival fonds and manuscript collections of mixed forms of materials, such as text, photographs, and sound recordings.
r - Three-dimensional artifact or naturally occurring object Code r indicates that the content of the record is for a three-dimensional artifact or a naturally occurring object. This includes man-made objects such as models, dioramas, games, puzzles, simulations, sculptures and other three-dimensional art works, exhibits, machines, clothing, toys, and stitchery. It also includes naturally occurring objects such as, microscope specimens (or representations of them) and other specimens mounted for viewing.
t - Manuscript language material Code a indicates that the content of the record is for manuscript language material or a microform of manuscript language material. This category is applied to items for language material in handwriting, typescript, or computer printout including printed materials completed by hand or by keyboard. At the time it is created, this material is usually intended, either implicitly or explicitly, to exist as a single instance. Examples include marked or corrected galley and page proofs, manuscript books, legal papers, and unpublished theses and dissertations.
008/26 - Type of computer file (006/09) A one-character alphabetic code indicates the type of electronic resource being described. The specific type of electronic resource is also described in textual form in field 516 (Type of Computer File or Data Note). A fill character (|) is used when no attempt has been made to code this 008 position.
a - Numeric data Code a indicates an electronic resource that contains mostly numbers or representation by numbers, such as records containing all information on student test scores, all information on football team statistics, etc. The information may be original surveys and/or information that has been summarized or statistically manipulated.
008/26 a
516 $a Numeric data
b - Computer program Code b indicates an electronic resource containing an ordered set of instructions directing the computer to perform basic operations and identifying the information and mechanisms required. This category includes videogames and microcomputer software and computer models. Some types of computer programs (e.g., game, font) are identified by separate codes in this character position.
008/26 b
516 $a Computer programs
c - Representational Code c indicates an electronic resource that contains pictorial graphic data that can be manipulated in conjunction with other types of files to produce graphic patterns that can be used to interpret and give meaning to the information. It does not include a document in image format.
008/26 c
516 $a Graphic data (Architectural drawings)
d - Document Code d indicates an electronic resource that is textual, consisting mostly of alphabetic information (words or sentences) converted into a coded format that can be processed, sorted, and manipulated by machine, and then retrieved in many optional formats. It includes language material intended to constitute a textual document, whether represented as ASCII or image data. It includes both single bibliographic entities or a collection of bibliographic entities. Documents whose primary purpose is textual, even if search software is present, are coded here.
008/26 d
516 $a Text (Law reports and digests)
e - Bibliographic data Code e indicates that an electronic resource consists of data with bibliographic citations. This includes data from library catalogs or citation databases. The data may be in a structured or unstructured form. Search software may be present, but the purpose of the record is description of the content of the bibliographic data or database, rather than description of the online system or service.
008/26 e
516 $a Library catalog
f - Font Code f indicates that an electronic resource contains information for a computer to produce fonts.
008/26 f
516 $a Fonts (Bitmapped and PostScript)
g - Game Code g indicates that an electronic resource is a game, intended for recreational or educational use. Generally games consist of text and software. A videogame is included here.
008/26 g
516 $a Computer game
h - Sounds Code h indicates that the file consists of data encoding sounds producible by the computer.
008/26 h
516 $a Audio (Digital audio file)
i - Interactive multimedia Code i indicates that the electronic resource described by the record supports navigation through and manipulation of many kinds of media (i.e., audio, video, etc.). Interactive multimedia usually gives the user a high level of control, often allowing almost conversational interaction with the computer and data.
j - Online system or service Code j indicates that the record is for an online system or service and may contain nonbibliographic information. An online system or service supports system-based user interaction. If the focus of the record is to describe the system itself, with the content of the databases incidental contained therein, it is coded here. If the resource is an online file where the system is incidental to the description, it falls into another category. Examples of online systems or services are: online library systems (consisting of a variety of databases), FTP sites, electronic bulletin boards, network information centers.
008/26 j
516 $a Campus-wide information system
m - Combination Code m is used when the item is a combination of two or more of the above types of files.
008/26 m
516 $a Computer programs and text files
u - Unknown Code u indicates that the type of file is unknown.
008/26 m
z - Other Code z indicates a type of file for which none of the other defined codes are appropriate.
