There is no special vacation loan, ie if you borrow now, you are still expected to return your books and CDs in 4 weeks time (or renew them online) and your DVDs in 2 weeks time.
So perhaps the best would be for you to return all items before you go on holiday? And please, do not travel with them… too many books return with dreadful sun burns and also indulged in dipping in swimming pools… no. Please. No.
(and no punting either with books, best way to learn a language in summer is to talk, talk, talk!)
