Is there a REST best practice for GETting resources in different languages. Currently, we have 

www.mysite.com/books?locale=en

I know we can use the accept-language header but is it better for us to do 

www.mysite.com/books/en or www.mysite.com/books.en

or does it not matter?

    I think best way would be to implement this following way:

    1. HTTP’s Accept-Language header
    2. Language prefix in URI such as /en/books/…

    In other words you can accept language from both sources. Implementation will be following:

    1. Check if Accept-Language header is provided and keep this in the variable;
    2. If request URI starts with /en, /fr or other known language codes(that are supported by your system) Overwrite language variable with this new value, strip it from URI i.e. if URI is /en/books you will end up with /books.
    3. If there is no language provided, keep default language in variable for example “en”

    With this approach you can make sure that a) path routing will be language agnostic and your system will work uniformly with paths; b) language handling/negotiation will be completely separated from your scripts. You can use language information in your scripts without even knowing what was the source and how it was requested.
