Philip's, one of the oldest publishing houses in the United Kingdom, was originally founded in 1834 as George Philip and Son. Philip's was, at one time, the owner of the world-famous Stanfords map store, and has now become part of the Octopus Publishing Group. Philip's built its reputation for quality mapping after having produced historical and long term market leaders such as the classic Philip's Modern School Atlas, now in its 95th edition. Philip's also publishes a range of specialist books, including the widest range of amateur astronomy books available. Every specialist product created by Philip's is written or compiled by an expert in that particular field, and, as such, are accurate, practical, up to date, well written and beautifully illustrated.
