Original language in book page and search

Description of your request or bug report:

I’d love to see on book pages (and even maybe series/movie pages) something specifying the original language it was written/filmed in. It’d be great if it was possible to input that in the search function as well.

Sometimes I want to read something that was originally written in English/my native language and then translated, to have a translation directly available. But other times, I’d rather read a book written directly in my target language that I wouldn’t have the opportunity to read otherwise, and that would likely have more relevant cultural elements.
