I found books were 'easy' on the first pass, but now I've been going awhile at this it gets harder because what I've got I feel like I either want to keep (that's fine) or I should at least try reading before they go or actually do want to read them but don't expect to want to keep them afterwards which makes it much slower. I think the post I'm making today might end up being the last 'big' lot of books to go en masse.
