024 - Other Standard Identifier (R)

Structure - ISRC usually appears on an item preceded by the letters ISRC. It consists of twelve alphanumeric characters structured as four elements separated by hyphens: 1) country; 2) first owner; 3) year of recording; and 4) recording. The country codes consists of two letters as specified in Codes for the Representation of Names of Countries (ISO 3166). The first owner code is alphanumeric and consists of three characters. The year of recording code consists of the last two digits of the year (e.g., 82 for 1982). The recording code consists of five digits and is assigned sequentially by the first owner.

Display Constants - Initialism ISRC, the phrase ISRC (invalid), and the internal hyphens are not carried in the MARC record. They may be system generated as display constants associated with first indicator value 0 and the content of subfields $a and $z, respectively.

Structure - UPC appears as a bar-code symbol with 12 digits printed below it. Hyphens or spaces susually separate the elements of the number on the item. The code has three basic parts. 1) The first digit is the Number System Character (NSC) which appears on the left side of the symbol outside of the bars. 2) The next ten digits encoded in the symbol are shown below the bars. 3) The twelfth digit is a check digit and usually appears at the bottom right of the symbol. All digits as found on the piece are input into MARC.

For audio and video products, the ten digits of part 2), printed below the parallel bars, consist of three elements: a five-digit manufacturer designation to designate the manufacturer assigned by the Uniform Code Council; a five-digit selection number; and a single-digit configuration number. The fifth digit of the first element serves as both the last digit of the manufacturer designation and the first digit of the selection number. The tenth digit (configuration number) indicates the format of the product.

For serials, the five digits after the NSC identify the publisher or distributor. The next five digits encode a BIPAD title identification number which uniquely identifies each publication. A two-character supplemental symbol designating a specific issue may follow the number.

For paperback books, there are two bar-coding structures. The ten digits of part 2) may consist of a five digit identifier for the publisher and the next five digits contain the title portion of the International Standard Book Number (ISBN). For the other, the first five digits of part 2) identify the publisher or the bookline, the next five digits represent a cover price or a price category. Five add-on digits may follow part 3); they are derived from the title portion of the ISBN.

Display Constants - UPC is carried in the MARC record without the internal hyphens or spaces. Hyphens, spaces and introductory words may be system generated as display constants associated with first indicator value 1 and the content of subfields $a, $d, and $z.

Structure - ISMN is an agency-assigned data element. ISMNs are assigned to music publications by designated agencies in each country participating in the program.

An ISMN consists of ten or thirteen digits. The 10-digit ISMN, used before 2008, is comprised of the letter M followed by 8 digits (variable length publisher number plus item number) plus a single character check digit. The check digit applies to the previous 8 digits.

The 13-digit ISMN, used since 2008, has the prefix 979 and a 0 to replace the M, then 8 digits plus the final check digit. The check digit applies to the previous 12 digits. A 13 digit ISMN is identical to the EAN-13 number encoded in the bar code. The structure is specified in ISO 10957.

An ISMN usually appears on an item preceded by the initialism ISMN and with functional parts separated by a hyphen or space.

Display Constants - Initialism ISMN, the phrase ISMN (invalid), and the embedded hyphens or spaces are not carried in the MARC record. They may be system generated as display constants associated with first indicator value 2 and the content of subfields $a and $z, respectively.

Structure - EAN has 13 digits. For serials, a three-digit prefix (977) is used in combination with the eight-digit International Standard Serial Number (ISSN) or with a nationally administered title number such as the BIPAD number in North America. A two- or five-digit add-on symbology to designate issues may be present.

For paperback books, a three-digit prefix (978) is followed by the first nine characters of the International Standard Book Number (ISBN), omitting the final ISBN check character. An all-numeric Modulus-10 check digit is the 13th character of the EAN. A five-digit supplement may be used to code additional data, e.g., price.

Display Constants - EAN is carried in the MARC record without the internal hyphens or spaces. Hyphens, spaces, and introductory words may be system generated as display constants associated with first indicator value 3 and the content of subfields $a, $d, and $z.

Structure - Serial Item and Contribution Identifier (SICI) is a variable length code that provides unique identification of serial issues (SII) and serial contributions (SCI). The SII consists of the ISSN, issue date, issue numbering, SICI standard version number, and a check character. The SCI adds the contribution location and a title code (if more that one title begins on a page) between the issue numbering and the SICI version number. The barcode version of the number on an item will differ from the eye-readable version.

Display Constants - SICI contains punctuation separating the sections of the identifier and they are recorded in the MARC record. Introductory words may be system generated as display constants associated with first indicator value 3 and the content of subfields $a and $z.
