Get Started

To get people reading or listening to your book as quickly as possible, just fill in the details and upload your files below. It'll then take half an hour or so for the processing at our end to complete, and in the meantime, you can log in to your Glassboxx account here. (When logging in for the first time, you'll need to use the 'Forgot Your Password' link to set a new password for yourself.)

The files you need are:-

1. A cover image should be a jpg/jpeg file, named as <ISBN-13>.jpg.

2. For an audiobook, mp3 files named as <ISBN-13>_nnn_MP3.mp3 where nnn is a 3 digit sequence number for the file within the audiobook. For example, for a book with ISBN 9781407951058, the track 1 file must be named 9781407951058_001_MP3.mp3 and the track 2 file must be named 9781407951058_002_MP3.mp3 etc.


3. For an eBook, an ePub named as <ISBN-13>.epub, and it is not necessary to include a cover image in it.

Finally, the mp3 and ePub files you upload here must not be bigger that 200MB each, and the overall size of the book must not exceed 800MB. (If your book is larger than this, contact us to find out about other options for you to send us your books.)
