For the MARC21 notes on this tag, refer here for ISBN or here for ISSN .
|a||9788478889938||Valid ISN for this format of this record. This is imported into the ISN field.
For ISBNs both the 10-digit and 13-digit ISBNs are saved for indexing. These can be seen by setting OLIB Defaults: Show Equivalent ISBN to "Yes".
Often both the 10-digit and the 13-digit ISBNs are present in the MARC record. Where they are equivalent, only the 13-digit will be held as the primary ISBN and only this version of the ISBN will export, unless the 10-digit version is manually catalogued since the import.
|c||£14.95||Terms of availability: This is imported into the Prices linked to the Title record. The original value is placed into the Price (Textual) field, with the numeric portion population a numeric price field that is not on standard layouts. The data that is not numeric is used to attempt to identify the currency by name, code or symbol.|
|q||paperback||Qualifying information: This is imported into the Qualification field on the ISNs record. This information may previously have been present in parentheses in the 'a' subfield (for records prior to 2013) and is imported from there into the Qualification field too, but will be exported in $q.|
|z||9788478889938||Cancelled / Invalid ISN: This is used, for example, for the Print ISBN associated with an e-Book. It is imported to and exported from the Invalid ISN field on the ISNs record and is not included for searching in OLIB.|
