Books (please note that I have no idea whether they are in print or not)

• "The Nature and Subsequent Uses of Flint: the basics of lithic technology", by John Lord.  An excellent introduction by a fine knapper.
• "The Joy of Flint", by C Waddington.  Another good introduction.
• "Tools of the Old and New Stone Age", by Jacques Bordaz.  Some helpful diagrams.  Despite the title, there is not much on the Neolithic period.
• "Flintknapping", by John Whittaker.  A very detailed "how to" book, but as John is American almost all of the photos and illustrations focus on their artefact types - very few British.
• A Stone-workers Progress".  A study of the implements in the Pitt Rivers museum.
• "Ancient Stone Implements of Great Britain", by John Evans.  This one is definitely out of print - its second edition was produced in 1897.  It is a lovely antiquarian book, with hundreds of beautiful woodcut illustrations of flint implements.  Expect to pay well over £50 for a good quality copy.
• "Prehistoric Flintwork", by Chris Butler.  Detailed descriptions of all of the main categories of British flint implements, written by one of the most skilled flint-diagnosticians in the UK.  Yours truly made all of the modern replicas shown in the book (see the "Gallery" for a better photo of the dagger on the cover) and it includes a photo of me knapping - wise man that he is, Chris decided to show my hands rather than my face.
