Good news it’s the ePub format that Chapters has chosen.

I was hoping for the Nook but so far theses are the supported eReader devices:

ePub files purchased on shortcovers.com can also be read on the following eReading devices:

* PRS-300 Reader Pocket Edition
* PRS-505 Reader Digital Book
* PRS-600 Reader Touch Edition
* PRS-700BC Reader Digital Book
* Asktak (EZ Reader, EZ Reader Pocket Pro, Mentor)
* BeBook (One, Mini)
* Bookeen (Cybook Opus, Gen 3)
* COOL-ER Classic
* Elonex eBook 600
* HanLin eBook (V3, V5)
* IREX Digital Reader 1000S
* Neolux NUUT2

The Canadian book will not miss this train and will be selling book too.

I’ll come back to you with more information about the format they will
be using.

At the first glance the title available look a lot like Eeader.com & Barnes & Noble
