This year the ISBN regional meeting of the Balkan group took place in Sofia, Bulgaria on 12 and 13 May 2015. Our kind hosts were the National Library St. Cyril and St. Methodius, which runs the Bulgaria ISBN Agency.

Delegates from the following agencies were present at the meeting:

• Bulgaria
• Croatia
• Montenegro
• Serbia
• Republic of Srpska
• Slovenia
• International ISMN Agency

Reports were given on the implementation of ISBN in the represented countries and, among other items, there were also updates and discussions concerning publisher data and progress on the revision of the ISBN standard. 

The International ISBN Agency would like to thank all colleagues at the National Library St. Cyril and St. Methodius for organising a wonderful meeting. Their help before and druing the event was invaluable. We would also like to thank all delegates for their attendance and participation.
