I think this needs a bit of revision:An 'Econimics' book would be about economy.
An 'Economical' would be a book that didn't cost you much, ie cheap
Well, thanks a lot for these links, CapnPrep!
In my context it's " Economics books"!!!I think this needs a bit of revision:
An Economics book is about Economics, not about economy.
An economical book is a strange concept: in what way is it economical? - if it's economical with the truth, it's a book full of lies.
