MARC 21 Concise Community Information: Location and Alternate Graphics Fields (8XX)

This is an ARCHIVED VERSION of the 2006 electronic edition of the MARC 21 Concise Formats. Please see www.loc.gov/marc/concise/ for the most up-to-date version of the electronic MARC 21 Concise Formats.

Fields 856 and 880 are the only 8XX fields defined in the MARC 21 Format for Community Information. These fields are defined analogously to similar fields in the other MARC 21 formats to record information about the location of a community information resource and the presence of alternate graphic representations of information in the MARC record.

• 856 - ELECTRONIC LOCATION AND ACCESS (R)
• 880 - ALTERNATE GRAPHIC REPRESENTATION (R)

Information for Translators and Other Users
Items highlighted in red indicate changes made after the 2005 edition of the MARC 21 Concise Formats was published and are included in the 2006 printed edition of the MARC 21 Concise Formats.

856 - ELECTRONIC LOCATION AND ACCESS (R)

The information required to locate an electronic community information entity. The information identifies the electronic location containing the item or from which it is available. It also contains information to retrieve the item by the access method identified in the first indicator position. The information contained in this field is sufficient to allow for the electronic transfer of a file, subscription to an electronic journal, or logon to an online resource.

Field 856 is repeated when the location data elements vary (subfields $a, $b, $d, when used). It is also repeated when more than one access method is used, different portions of the item are available electronically, mirror sites are recorded, different formats/resolutions with different URLs are indicated, and related items are recorded.

See the Guidelines for the Use of Field 856 for a more thorough discussion on the use of field 856.

Indicators

• First - Access method
  A value that defines the access method to the electronic resource. If the resource is available by more than one access method, the field is repeated. When recording a URL in subfield $u, the value corresponds to the access method (URL scheme), which is also the first element in the string.
  • # - No information provided
  • 0 - Email
    Access to the electronic resource is through electronic mail (email).
  • 1 - FTP
  • 2 - Remote login (Telnet)
  • 3 - Dial-up
    Indicates that access to the electronic resource is through a conventional telephone line.
  • 4 - HTTP
    Indicates that access to the electronic resource is through the Hypertext Transfer Protocol.
  • 7 - Method specified in subfield $2
• Second - Relationship
  A value that identifies the relationship between the electronic resource at the location identified in field 856 and the item described in the record as a whole. Subfield $3 is used to provide further information about the relationship if it is not a one-to-one relationship.
  • # - No information provided
  • 0 - Resource
    Indicates that the electronic location in field 856 is for the same resource described by the record as a whole. In this case, the item represented by the record is an electronic resource. If the data in field 856 relates to a constituent unit of the resource represented by the record, subfield $3 is used to specify the portion(s) to which the field applies.
  • 1 - Version of resource
    Indicates that the location in field 856 is for an electronic version of the resource described by the record. In this case, the item represented by the record is not electronic but an electronic version is available. If the data in field 856 relates to a constituent unit of the resource represented by the record, subfield $3 is used to specify the portion(s) to which the field applies.
  • 2 - Related resource
    Indicates that the location in field 856 is for an electronic resource that is related to the item described by the record. In this case, the item represented by the record is not the electronic resource itself. Subfield $3 can be used to further characterize the relationship between the electronic item identified in field 856 and the item represented by the record as a whole.
  • 8 - No display constant generated

Subfield Codes

• $a - Host name (R)
  The fully qualified domain (host name) of the electronic location. It contains a network address which is repeated if there is more than one address for the same host.
• $b - Access number (R)
  The access number associated with a host. It can contain the Internet Protocol (IP) numeric address if the item is an Internet resource, or a telephone number if dial-up access is provided through a telephone line. This data changes frequently and is generated by the system, rather than statically stored.
• $c - Compression information (R)
  Information about the compression of a file, in particular, whether a specific program is required to decompress the file.
• $d - Path (R)
• $f - Electronic name (R)
• $h - Processor of request (NR)
  The username, or processor of the request; generally the data which precedes the "@" in the host address.
• $i - Instruction (R)
  An instruction needed for the remote host to process a request.
• $j - Bits per second (NR)
• $k - Password (NR)
• $l - Logon (NR)
  Characters needed to connect (i.e., logon, login, etc.) to an electronic resource or FTP site. This subfield is used to record general-use logon strings which do not require special security.
• $m - Contact for access assistance (R)
• $n - Name of location of host (NR)
  The full name of the location of the host in subfield $a, including its geographical location.
• $o - Operating system (NR)
• $p - Port (NR)
  The portion of the address that identifies the process or service in the host.
• $q - Electronic format type (NR)
  An identification of the electronic format type, which is the data representation of the resource, such as text/html, ASCII, Postscript file, executable application or JPEG image. Electronic format type may be taken from enumerated lists such as registered Internet Media Types (MIME types).
• $r - Settings (NR)
• $s - File size (R)
• $t - Terminal emulation (R)
• $u - Uniform Resource Identifier (R)
  The URI, which provides standard syntax for locating an object using existing Internet protocols. Field 856 is structured to allow for the creation of a URL from the concatenation of other separate 856 subfields. Subfield $u may be used instead of those separate subfields or in addition to them.
  Subfield $u may be repeated only if both a URN or a URL or more than one URN are recorded.
• $v - Hours access method available (R)
• $w - Record control number (R)
• $x - Nonpublic note (R)
• $y - Link text (R)
• $z - Public note (R)
• $2 - Access method (NR)
• $3 - Materials specified (NR)
• $6 - Linkage (NR) See Control Subfields
• $8 - Field link and sequence number (R) See Control Subfields

880 - ALTERNATE GRAPHIC REPRESENTATION (R)

The full content-designated representation, in another script, of another field in the same record. Field 880 and the associated roman field both contain a subfield $6 (Linkage). The first and second indicator positions in field 880 have the same definition and values as the indicators in the associated field. The subfield codes in field 880 are the same as those defined in the associated field except for subfield $6.

Indicators

• First - Same as associated field
• Second - Same as associated field

Subfield Codes

• $6 - Linkage (NR) See Control Subfields
• $a-z - Same as associated field
• $0-5, Same as associated field
• 7-9 - Same as associated field
