856 Electronic Location and Access Repeatable

Optional

First indicator:

Access method. Contains a value that defines how the rest of the data in the field will be

used. The value in this indicator position determines which subfields are appropriate.

b No information provided

Indicates that no information about access method is provided. This value is used when subfield g contains a URN and there is no URL recorded in subfield u. When subfield u contains a URL and subfield g is also present with a URN, the indicator value for the appropriate access method of the URL is given. If using a URL in subfield u with one of the

access methods that has a value defined in the first indicator, the access method may be

repeated in subfield 2 if desired. (e.g. 856 0 ‚umailto: ‚2mailto)

0 Email

Indicates that access is through the Mail Transfer Protocol (MAILTP).

1 File Transfer Protocol (FTP)

2 Remote login (Telnet)

Indicates that access is through remote login using an application such as 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 Source specified in subfield 2

Value 7 and subfield 2 file is used for electronic access to host-specific file names (i.e.,

files stored locally). This designation is also a defined URL scheme.

Second indicator:

Relationship. Contains 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.

b 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 bibliographic 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 bibliographic record is not electronic but an electronic version is available.

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 bibliographic 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 bibliographic record as a whole.

8 No display constant generated

856 Electronic Location and Access p. 2

Subfield codes:

R ‚a Host name

Contains 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. The convention for a BITNET address is to add .bitnet.

‚b Access number

Contains 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.

R ‚c Compression information

Contains information about the compression of a file, in particular, whether a specific program is required to decompress the file

R ‚d Path

R ‚f Electronic name

R ‚g Uniform Resource Name

Contains the URN for the electronic resource. A URN provides a globally unique location- independent identifier that can be used for identification of the resource and thus facilitates access to the resource. The content of the subfield includes the initials "urn".

‚h Processor of request

Contains the username, or processor of the request; generally the data which precedes the "@" in the host address.

R ‚i Instruction

Contains an instruction needed for the remote host to process a request.

‚j Bits per second

‚k Password

‚l Logon/login

Contains characters needed to connect (i.e., " logon", " login", etc. to an electronic resource or FTP site. For many general-use File Transfer Protocol servers, access is gained by entering the string "anonymous". An account number required for login may also be indicated. This subfield is used to record general-use logon strings which do not require special security.

R ‚m Contact person for access assistance

‚n Name of location of host in subfield a

Contains the full name of the location of the host in subfield a, including its geographical location

‚o Operating system

‚p Port

Contains the portion of the address that identifies the process or service in the host.

‚q File transfer mode

Contains 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. The intent of specifying this element is to provide information necessary to allow people or machines to make decisions about the usability of the encoded data (what hardware and software might be required to display or execute it, for example). The electronic format type also determines the file transfer mode, or how data are transferred through a network. (Usually, a text file can be transferred as character data which generally restricts the text to characters in the ASCII (American National Standard Code for

856 Electronic Location and Access p. 3

Information Interchange (ANSI X3.4)) character set (i.e., the basic Latin alphabet, digits 0- 9, a few special characters, and most punctuation marks) and text files with characters outside of the ASCII set, or non-textual data (e.g., computer programs, image data) must be transferred using another binary mode.) Electronic format type may be taken from enumerated lists such as registered Internet Media Types (MIME types).

‚r Settings for data transfer

R ‚s File size

R ‚t Terminal emulation

‚u Uniform resource locator (URL)

Contains the URL, which provides standard syntax for locating an object using existing Internet protocols. Field 856 is structured to create a URL from separate subfields.

R ‚v Hours access available

R ‚w Record control number for online services

R ‚x Non-public note

R ‚z Public note

‚2 Source of access

‚3 Materials specified

Subfield 3 is used to specify to what portion or aspect of the resource the electronic location

and access information applies. Specific situations may be:

A portion or subset of the item is electronic. Examples: ‚3table of contents; ‚3v. 2-5;

‚3abstract; ‚3b&w copy negative

A related electronic resource is being linked to the record. Example: ‚3author's self-portrait

‚6 Linkage

Notes:

This field contains the required information to identify, locate and retrieve an electronic item. The data in this field allows for the electronic transfer of a file, the subscription to an electronic journal or logon to an electronic resource. In some cases only unique data elements are recorded which allow the user to access a locator table on a remote host containing the information needed to access the item.
Field 856 is repeated when the location data elements (subfields a, b and d) vary or when more than one access method may be used. It is also repeated when the electronic filename (subfield f) varies, except when a single intellectual item is divided into different parts for online storage or retrieval.
Telephone numbers are recorded in subfield b as follows:[country code]-[area code]-[telephone number]. Example: 61-49-215833 (a number in New South Wales, Australia); 1-202-7076237 (a number in Washington, D.C.). If an extension is applicable, include it after the telephone number preceded by x. Example: 1-703-3589800x515. Codes used in subfield 2 specify the

access method used to locate an electronic item.

The codes used are:

file Host specific file name

gopher Gopher protocol

news USENET news

nntp USENET news using NTTP access

prospero Prospero Directory Service

wais Wide Area Information Servers
