After all, the NYT bestseller list is based (so they tell us) on anonymous and supposedly widely sourced data
from a lot of
bookstores, and wholesales who retail to
other outlets... And has: 1) reputedly been cooked before 2) As we don't know the methodology is hard to check — but we know some very popular books never make it, and books which don't sell that many copies (17K hardback was reputed to get you
onto the extend list, according to a friend who got there on that) 3) We know Bookscan data is pretty close to GIGO — so it's hard to see where the NYT would get better data.
The iRex can also handle the ePub file format, a widely accepted industry standard, which means that owners can buy books
from other online
bookstores that use ePub and transfer texts
onto the iRex.
