Book numbers and bar-codes

Publishers—especially small publishers—should be aware that some bookshops will not stock a book unless it has a bar-code incorporating the ISBN (international standard book number) printed on the back cover or jacket. Bar-codes are also used by libraries.

Unlike most countries, Ireland has no national ISBN agency; the Irish publishing industry chooses to operate under the British ISBN Agency, which assigns the appropriate codes to Irish publishers. This service, previously free, now incurs a charge of £94 (minimum).

After an ISBN has been allocated to your book, we can create the bar-code image (in EPS or any other format). Alternatively, if you wish to do this yourself you can download our free Opentype font Valida, together with instructions on how to calculate the numbers and create your own bar-codes.
