Implicating blue_books -> blue_book.

Reason: Many implies at least one

Denied

I'm not entirely sure we even need the blue_books tag, let alone implicating it to blue_book.

I'm not sure that either tag is even needed, honestly. I'd say alias both to "book".

There is was just one instance of both of them and it's unlikely that someone will use it in future. Is alias really necessary?

Agree with the others, it should just be book.....unless we have a few book racists out there who cant stand the sight of a black book and just want to look up blue books....jk lol
