The ISBN agency will be closed from midday on 22 December 2017 to 2 January 2018.
Throughout this time, however, you will still be able to purchase ISBNs, barcodes and other self-publisher products and services via the MyIdentifiers website.
For any urgent queries email firstname.lastname@example.org, using your ISBN as a reference. The team will respond as soon as possible when the agency reopens.
The ISBN team would like to wish you a happy festive season.
