The world-famous Oxford Union is rightly proud of its library. Of course, Oxford is full of libraries crammed with rare copies, beautiful interiors and terrifyingly intelligent academics. This fits the mould, but is a healthy mixtures of generally artsy books. In keeping with the general theme of the union, it's well-loved by law and politics students, although there's something for most subjects. It's one of the biggest libraries where you can borrow books (as opposed to sit in there and read them) in Oxford, but its use is limited to members of the Union, for which it is necessary to pay over £100.
There's also a decent collection of fiction, which can be a bit lacking in college libraries. It's got books written in the past few years. The travel guides are particularly useful, although quickly outdated, as are the magazines and newspapers. They're generally quite serious magazines (although FHM has been known to make an appearancE) - more the Economist and New Scientist than Heat or Hello, and much cheaper than buying one which you'll read once.
If you're not a member of the Union or the Union Society, you can still visit the library for £1.50 and it's well worth doing so to see the Pre-Raphaelite murals (1857-9) painted by Rossetti, Edward Burne-Jones and William Morris. They're all quite dramatic and mostly related to the legends of King Arthur. Don't forget to look up at the ceiling! read more
