The usual squinting in half-light to see street names in the index is eliminated with a very clear font in a good size. Perhaps best of all is the range: Greater London is given a remarkably generous definition, then stretched a bit further to include Gatwick airport. There's every street from Windsor and Amersham to Gravesend and Romford, from Hertford and Harlow to Crawley and Guildford. A4 in size and an inch thick, the book is robustly built for the hammering most drivers are likely to give it, although not such a good size for the walker or cyclist. --Rebecca Pickering
