Publisher Services was fast and easy for my ISBN number assignment and bar code delivery. Within 5 minutes after my ISBN bar code arrived my book cover was completed and ready for printing. Thanks for the great services.

Publisher Services couldn't have made my purchase of an ISBN number any easier. I called first with a question and was met with friendly and competent help. I would recommend them without hesitation and will use their services again.

As a self-published author, getting my bar code was crucial! The customer service helped me make the right choices! I've referred many authors who want their own bar codes to this site!

Publisher Services made it extremely easy and affordable for me to attach an ISBN number and bar code to my first book without having to spend a lot of money–money I would rather put toward printing extra copies of the book itself. Thank you for providing a sane option to writers who are just starting out!
