One of the best reference books for stone tools is that great work, Ancient Stone Implements of Great Britain, by Sir John Evans published in 1897. This brilliant Victorian book has hundreds of finely detailed drawings of implements of every kind and is invaluable to anyone wanting to identify a stone tool. Unfortunately, it has been out of print for many years and only available from antiquarian book sellers at anything from £50 to £100 or more because of the beautiful illustrations. I was very fortunate to discover a copy in Charing Cross Road twenty years ago for only a tenner.
Now I’m pleased to see that a publisher in India has reprinted it in paperback form and it’s available on Amazon for around £21 plus second hand versions. Well worth a look.
