This list is a lot less fun than Munro's, as it leaves no scope for arguments about which summits should be promoted to separate mountain status or relegated to being only 'tops'. Corbett's list was passed on to the editors of Munro's Tables after his death, and there is no record of why he chose 500 feet as the amount required to separate one hill from another. Like Munro, Corbett was concerned only with Scotland. This list is also published in the book of Munro's Tables . George Bridge published a book listing all the summits in England and Wales over 2000 feet high, using a formula based on a combination of height difference and distance apart to decide which summits to include.
Recent maps show that it is now well out of date.
A small booklet published by Chris Buxton and Gwyn Lewis in 1986 lists all the summits in England and Wales over 2000 feet high with a minimum of only ten metres drop all round. Writers of guidebooks such as the renowned Alfred Wainwright and Walter Poucher have included lists of prominent and well-known summits, based on no particular criteria. These are excellent and worthwhile guidebooks, but are not intended to be definitive references. A separate booklet listing all the summits named in Wainwright's books was published by John Turner, but this is intended as an index and does not attempt to rationalise any of the details. In 1989 Eric Yeaman produced a handbook listing all the Scottish hills that have a drop of 100 or more metres on all sides, together with others qualifying by distance instead of relative height.
