No, only acquirements and gifts. As I wrote in the other mail, book 
generation methods should be different between acquirement and god and 
floor: the former two should produce randart books much more often than 
the latter.

For books on the floor, choose level either random or better yet, random 
but depending on depth (whichever is used for current spellbook 
generation). Set c=1 (i.e. known/unknown has no effect for randart books 
on the ground). No additional tries are necessary, of course.

For acquirements, the item_level should affect level.
