This is getting incredibly frustrating. Every time I want to try to translate something recently, I'm stumped by one word and just can't think of how to put it in English... Even if I can find it in a dictionary.

EDIT: This time it was the 'halfhearted' in the last pannel

Do they say "books unnecessary" or "unnecessary books"?

No now that I look again, are they saying "books unnecessarily"?
