024  Other Standard Identifier (R)

International Standard Recording Code (ISRC). The ISRC usually appears on an item preceded by the letters ISRC. It consists of 12 alphanumeric characters structured as the following four elements separated by hyphens on the item:

• Country code, from ISO 3166, Codes for the Representation of Names of Countries
• First owner of recording, consisting of three alphanumeric characters
• Year of recording code, consisting of the last two digits of the year (e.g., 82 for 1982)
• Recording code, consisting of five digits, assigned sequentially by the first owner

Do not enter the initials ISRC or the hyphens between numbers. Use 1st indicator value 0.

Universal Product Code (UPC). The UPC appears as a barcode symbol with 12 digits printed below it. Hyphens or spaces usually separate the elements of the number on the item. The code has three basic parts:

• First digit, the Number System Character (NSC) which appears on the left side of the symbol outside of the bars
• Second through eleventh digits, encoded in the symbol below the bars
• Twelfth digit, a check digit usually appearing at the bottom right of the symbol

The three basic parts of the UPC may be differently configured depending upon the kind of resource with which it is associated.

• For audio and video products, the ten digits of part 2, printed below the parallel bars, consist of three elements: a five-digit code that designates 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 that 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. In one barcode structure, the ten digits of part 2 may consist of a five-digit identifier for the publisher. The next five digits contain the title portion of the ISBN.
• For the other barcode structure, the first five digits of part 2 identify the publisher or the bookline, the next five digits represent a cover price or price category. Five add-on digits may follow part 3. They are derived from the title portion of the ISBN.

Do not enter the initials UPC, hyphens, or spaces.

International Standard Music Number (ISMN). 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.

Do not enter the initials ISMN, hyphens, or spaces.

International Article Number (EAN). The EAN has 13 digits. The first three digits are the EAN Prefix, representing a country or region or a broad class of materials such as serials or paperback books. The next nine digits comprise the company prefix and the item number. An all-numeric Modulus-10 check digit is the 13th character of the EAN.

• 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 symbol 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. A five-digit supplement may be used to code additional data, e.g., price.

Do not enter the initials EAN, hyphens, or spaces.

Serial Item and Contribution Identifier (SICI). The SICI is a variable length code that provides unique identification of serial issues (SICI) and serial contributions (SCI). The SICI 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 than one title begins on a page) between the issue numbering and the SICI version number. The SICI version associated with the barcode differs from the strictly eye-readable version of the SICI, so there will often be two SICIs in a single bibliographic record.

Enter SICI numbers with punctuation separating the sections of the identifier as found in the number. Do not enter the initials SICI.

Source specified in subfield ǂ2. The source of the number or code is specified in subfield ǂ2. Prefer use of the specific indicators 0-4 over the corresponding Standard Identifier Source Code in subfield ǂ2.

Unspecified type of standard number or code. The type of standard number or code is unspecified. Use 1st indicator 8 only in cases where there is neither an appropriate specific 1st indicator nor a MARC Standard Identifier Source Code assigned to that standard identifier.

No information provided. No information is provided about the form of the scanned and eye-readable numbers. Use also when the eye-readable number does not appear in a form adequate for scanning.

No difference. The scanned number and the eye-readable version are the same.

Difference. The scanned number and the eye-readable version are different.
