In reference to one question asked of the last post, we don't actually have more information on the status of the previously printed volumes yet, I meant "Keep reading..." in a general sense.
To clarify, however, we are contractually obliged not to sell the books individually or in any way except as a complete set. This may mean we will have to request the original volumes be returned at our cost, naturally, but we'll have to see if that's necessary (also entirely leaving aside the question of how easily we will be able to make people return books...)
