You can obtain an ISBN number from different sources, the most common being Nielsens – The UK’s ISBN provider. However buying from them is expensive, and one number will cost you over £95.

However, Compass Publishing offers single ISBN numbers for as little as £42.50 – and they can be bought straight away. If this is of interest to you, then simply get in touch by emailing us at, or you can call us at 02392 378625. You will need to declare your ISBN number on your title verso page and Compass Publishing will be your publisher. (However, we don’t retain any rights to your work, but we do register your books details with Nielsens once your book is printed)
