" He achieved fame by winning a celebrated match against the French champion St Amant, gave his name to a set of chessmen that has become standard, edited the first English chess magazine and by his originality and enthusiasm brought about the first International Chess Tournament. This remarkable man was Howard Staunton, the only British chess master of whom it could be said that at one time he was the world's leading player." "In 1847 came Staunton's first and greatest work on chess, the Chess-Player's Handbook. It was at once an immense success and remained so throughout his lifetime and long after. In between the years 1847 and 1935 it was republished 21 times." Harry Golombek
The main attraction of this book is as a historical document. It's fun to see how chess books have changed since Staunton's times. Some things are different, some are the same. You can also see how the whole ideology of how to write study books has changed.
The strategy and tactics are out of date, and I'd recommend using software if you really want to learn chess these days.
