979-ISBN-13 are in use in the Canadian supply chain and they have no corresponding ISBN-10 value. Therefore an ISBN-10 can no longer represent all book products in our market . and BookNet Canada can no longer recommend that ISBN-10 be used in data exchanges for new book records. Some end users may still ask for ISBN-10. If you are using 979-ISBNs you should ensure that they have the capacity to use your identifier, but there is no harm in supplying ISBN-10 on 978-ISBNs and some software will automatically include them. (Note: be Be sure your software doesn't attempt to create an ISBN-10 based on a 979 ISBN-13.)
How Do I Convert ISBN-10 to a 978-EAN/ISBN-13?
- First: A reminder that you cannot convert a 979-ISBN-13 to ISBN-10. Only 978-ISBN-13 can have a corresponding ISBN-10. ISBN-10s can only be converted to a 978-ISBN-13.
- Second: An observation that conversion utilities that support ISBN-10 are disappearing and you should not rely on ISBN-10. ISBN-13 is the only active ISBN type in the Canadian market
- Pragmatically there remains a need to work with legacy data so here's some remaining resources that might help
- For single conversions either way: http://www.isbn.org/converterpub.asp
Here is a useful Excel spreadsheet bulk converter ISBN10-13 Converter.xls (the orginal original source of this document follows but this link is no longer active: http://dynamicorange.com/2007/02/12/isbn-1013-converter-in-excel/)
While this conversion spreadsheet works, GREAT CARE MUST BE TAKEN when converting ISBN-10s with leading zeros OR that may be loaded as 9 (or fewer) digit numbers (which may have happened on the data already). legacy data held in Excel spreadsheets often has it's leading zeros stripped). The spreadsheet makes no allowance for this.
Using 0-538-75077-4 as an example for both problems:- 10 digit ISBN-10 0538750774 loses it's zero and becomes 9 digit 538750774
- The spreadsheet assumes all numbers are 10 digits and strips off the tenth number as it's the (a check digit) and then re-calcuate the correct check digit for the 978-ISBN-13
- 0538750774 should become 053875077 but if the column contains 538750774 as a 9 digit number it is simply transferred (the spreadsheet doesn't prevent transfer of a 9 digit number)
- The resulting ISBN-13 calculation can proceed on the incorrect number and create different results. There is only one correct match for 0-538-75077-4
