In terms of libraries, there is no need to worry (or spend a penny!). The University Library is a copyright library and has a copy of every book ever printed in the UK, then there are college libraries and Faculty libraries, meaning the books that you need are always available. The libraries are also great places to work in and welcoming and helpful. Sports facilities are widely available in Cambridge, whether it's gyms, playing fields, tennis courts etc. If you're interested in sport, I'd strongly advise you to join a club/society within Cambridge - a great way to meet people, use the best facilities, keep fit and a break from work. Some of the buildings in Cambridge are a little out-dated...but then it was established in the medieval period! I have found that whilst buildings may have been built in the 15th century, the university/colleges tend to have updated them on the inside so that there is not total modernisation, but also avoids the disadvantages of old buildings.
