From the outside, Blackwell's looks quite small, although not as small as when it first opened in 1879 when only three people could fit in the shop! However, don't let its appearance prevent you from entering. Downstairs, the Norrington Room, with its 160,000 books, is the largest room in Europe devoted entirely to book sales. Blackwell's is almost guaranteed to have the book you're looking for, and if by any chance they haven't, they'll order it for you.
Oxford Heritage runs this little shop called Hoyle's which is a treasure-trove of games of all descriptions, varying in price. There are jigsaws, puzzles, marbles, chess sets and books on how to play them all. Other than traditional family games there are also board games based on television shows. Pick up a miniature version of a classic to play while traveling, or invest in some magnetic poetry for your fridge.
