Troubleshooting
The ISBN from the Ministry is not accepted
Causes and fixes when entering the ISBN warns that the number is not valid, does not belong to Türkiye or is used on another record.
The Enter the ISBN dialog checks the number before saving it and shows any problem in the dialog. Check the causes below.
The check digit does not match
The number may have been mistyped. Check the number again on the screen of the Ministry of Culture and Tourism. Use digits, hyphens and spaces only.
The number is not in one of Türkiye's groups
ISBNs assigned in Türkiye start with 978-605, 978-625, 978-975 or 978-9944. Once the range message (the International ISBN Agency's file of ISBN ranges) has been fetched, the registrant range of the number is checked too. The dialog says which group the number belongs to. Enter the number again exactly as the Ministry's screen shows it.
If the range message has not been refreshed for more than three weeks, a number it does not know is not refused. The number is saved with a warning. The details are in Entering the ISBN.
The number is recorded elsewhere
If the number is recorded on another request or another catalogue record, the dialog shows a link that opens that request or record. If the number was entered on the wrong record, correct that record first.
The button is missing
