Did he get the Vmax new? We have the Vmax with eyegaze - ours came with a free book downloads from ebooks (or something like that). We had to pay a $50 registration fee and get a disability verification from the doctor - but my husband downloads books for free to read on it.
Hubby gets his books from Amazon - some he downloads from the internet (ebooks) and some he orders the book on disk. You may also want to check with your local library :0)
