The law library is at palace green, a 10 minute walk away.
Most law students don't use the library much though it seems, articles are all online and there's a core textbook for each module I think. (Seem to remember that from my law friends' bookshelves!)
All teaching is done by the dept so nothing is through your college. So lectures and tutorials are with people from every college, there isn't any differentiation. Not all tutors are even affiliated to a college, if they are it'll be just for pastoral things.
Facilities and functions - kitchens in every corridor, 3 music rooms (with pianos), big common room with mirrored walls, bar, theatre/hall, tennis courts, squash court, netball courts, boat house (for rowing).
And gardens for sunbathing in
