Despite digital restoration, many of the images above are of less than ideal quality. Should better copies come to hand, the files will be updated. Meanwhile some 1000 more images are currently being prepared for the next major update to this and other 'image' based pages. (proposed for early to mid 1998)
As time permits, the intention is to also add sound files to this page. Once again, these files will be of varying quality depending on the original recording and 'number of generations removed' my copy is from the original.
April, 1997
This project is still being continued (post doctorate) and will attempt to indeed add further material as time permits. Thankyou.
