Annex C. UKMARC Fields for Cataloguing Electronic Publications

Examples

1. 542.00 $aMode of use: On-line video or teletype terminal or with a small dedicated computer (e.g. PDP8)

The 856 field contains the information required to locate an electronic item. 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 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 remaining information needed to access the item.

Notes

1. The field is repeated when the location data elements vary (subfields $a, $b, $d) and when more than one access method may be used. It is also repeated whenever the electronic filename varies (subfield $f), except when a single intellectual item is divided into different parts for on-line storage or retrieval.

2. Subfield $b 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 may change frequently and may be generated by the system, rather than statically stored. Subfield $b may be repeated if all the other information in the field applies. A telephone number is recorded 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 the U.S., Washington, D.C.). If an extension is applicable, include it after the telephone number preceded by "x". Example: 1-703- 3589800x515 (telephone number with extension).

3. Subfield $f contains the electronic name of a file as it exists in the directory/subdirectory indicated in subfield $d on the host identified in subfield $a. Subfield $f may be repeated if a single logical file has been divided into parts and stored under different names. In this case, the separate parts should constitute a single bibliographic item. In all other cases, a file that may be retrieved under different filenames contains multiple occurrences of field 856, each with it corresponding electronic name in subfield $f. A filename may include wildcard characters (e.g., "*" or "?") if applicable, with a note in subfield $z explaining how files are named. NOTE: Filenames may be case sensitive for some systems. This subfield may also contain the name of the electronic publication or conference.

4. Subfield $g contains the name of the last physical file in an ordered sequence when the resource is contained in more than one physical file. This subfield is used when repetition of subfield $f is not possible.

5. Subfield $h contains the username, or processor of the request; generally the data which precedes the at sign ("@") in the host address.

6. Subfield $i contains an instruction or command needed for the remote host to process a request.

7. Subfield $j contains the lowest and highest number of bits (binary units) of data that can be transmitted per second when connected to a host. The syntax for recording the number of bits per second (BPS) should be: -. If only lowest given: - ; If only highest given: -.

8. Subfield $k is used to record general-use passwords, and should not contain passwords requiring security.

9. Subfield $l is used to record general-use logon/login strings which do not require special security.

10. For informational purposes, the operating system used by the host specified in subfield $a is indicated in subfield $o. Conventions for the path and filenames may be dependent on the operating system of the host. For the operating system of the resource itself (i.e., the item represented by the title recorded in field 245), rather than the operating system of the host making it available, field 753 (Technical Details Access to Computer Files), subfield $c (Operating system) is used.

11. Subfield $p contains the portion of the address that identifies a process or service in the host.

12. Subfield $q contains an identification of the file transfer mode, which determines 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 Information Interchange) character set (i.e., the basic Latin alphabet, digits 0-9, a few special characters, and most punctuation marks). Text files with characters outside of the ASCII set, or non-textual data (e.g., computer programs, image data) must be transferred using another file transfer mode, usually binary mode

13. Subfield $r contains the settings used for transferring data. Included in settings are: 1) Number Data Bits (the number of bits per character); 2) Number Stop Bits (the number of bits to signal the end of a byte); and 3) Parity (the parity checking technique used). The syntax of these elements is: -- If only the parity is given, the other elements of settings and their related hyphens are omitted (i.e., ""). If one of the other two elements is given, the hyphen for the missing element is recorded in its proper position (i.e., "--" or "--")
    The values for parity are: O (Odd), E (Even), N (None), S (Space), and M (Mark).

14. Subfield $s contains the size of the file as stored under the filename indicated in subfield $f. It is generally expressed in terms of 8-bit bytes (octets). It may be repeated in cases where the filename is repeated and directly follows the subfield $f to which it applies. This information is not given for journals, since field 856 relates to the entire title, not to particular issues.

15. Subfield $u contains the Uniform Resource Locator (URL), which provides electronic access data in a standard syntax. This data can be used for automated access to an electronic item using one of the Internet protocols. Field 856 is structured to allow the creation of a URL from the concatenation of other separate field 856 subfields. Subfield $u may be used instead of those separate subfields or in addition to them. Subfield $u may be repeated if the other information in the field applies.

16. If the record is for a system or service, the hours of availability are recorded in field 307 (Hours, etc.) and not subfield $v.

17. Subfield $y contains the access method when the first indicator position contains value 7 (Method specified in subfield $y). This subfield may include access methods other than the three main TCP/IP protocols specified in the first indicator. The data in this subfield corresponds with the access schemes specified in Uniform Resource Locators (URL) (RFC 1738), a product of the Uniform Resource Identifiers Working Group of the IETF. The Internet Assigned Numbers Authority (IANA) maintains a registry of URL schemes and defines the syntax and use of new schemes; the British Library will include an authoritative list based on that standard in USMARC Code List for Relators, Sources, Description Conventions.
