Anyone happen to know?
I'd recommend holding off on getting any books for now. Both of the RVC libraries are very well stocked and you can take up to 10 books out and renew them up to 50 times so it's not necessary to have your own copies, plus even if you do want your own it is a good idea to at least borrow them first so that you know which textbooks you like the most. If you do decide to buy then you can get them cheap from other students, or if you're desperate for new copies then the library can do a bulk order and get a discount.
Best of luck for the start of your studies!
