A little word of warning to students: the written material on this site is copyright.  You may not copy it and use it as your own work!  Please – if you are wishing to use any written material for publication in a book, TV or radio programme or on-line, feel free to ask and I shall try to be as helpful as possible.

Do not assume that any images are free to be copied or used elsewhere.  Most have been sent to me with the intention of being used only on this website and I can’t say it is OK to use them anywhere else.  Some are personal photographs, others may have been copied from publications without my knowledge.

Please don’t write to me asking for permission to use the images.  That permission is not mine to give.  If you believe that you own the copyright to any image displayed here and wish it to be removed – or just perhaps given a credit if one is missing – I will of course be happy to oblige.  Many of the illustrations are copyrighted by their respective copyright holders according to the original copyright or publication date as printed on the artwork or publication and are reproduced here simply for historical reference, educational and research purposes.
