In some cases, you are invited to download materials. For example, the Enigma worksheets in the Enigma Project section are for teachers to download to use and the pictures in the press section are for journalists.

In other cases, I am happy for material from the site to be quoted to a level of 'fair usage' where it is obvious that I have written material especially for the website.

However, please be aware that some material on this site has been used courtesy of a third party. For example, some of my book reviews and articles belong to a particular publication and the copyright still resides with the original publisher.
