|Field Name:||Standard Number (See below)|
|Dublin Core (DC) Mapping:||dc.identifier|
|MARC Mapping:||024 [8 ] $a (or if collection is all of one type, 001, 010 $a, 020 $a, 022 $a, 024 [1 ] $a, 028 $a)|
|CONTENTdm Data Type:||Text|
|Dublin Core Definition:||An unambiguous reference to the resource within a given context. Recommended best practice is to identify the resource by means of a string conforming to a formal identification system.|
|UA Definition:||This element is used only for standard numbers such as ISBN, UPC (Universal Product Code, aka barcode), ISSN, LCCN, OCLC, or music publisher number that are associated with the resource.|
When this element is used, prefer assigning a field name that specifies which type of standard number is to be recorded, rather than “Standard Number.” Use one of the following terms if applicable: “ISBN,” “Music Number,” “ISSN,” “LCCN,” “OCLC,” or “UPC.” For other types of numbers, devise an appropriate label.
Use separate elements, each with its own label, when more than one type of number is to be recorded.
If multiple values will be entered for a single type (e.g. ISBN 10 and ISBN 13), separate each with a semicolon space.
Enter ISBNs and UPCs without intervening spaces or punctuation. ISSNs should be recorded as two groups of four digits, separated by a hyphen. If the final digit of an ISBN or ISSN is an “X,” enter in uppercase.
Music publisher numbers should be given exactly as found, including alphabetical prefixes or suffixes, spacing, capitalization, and punctuation.
LCCNs should also be entered exactly as found, including alphabetical prefixes and internal spacing. However, omit spaces that might precede the number.
