Book Purchase Information
Currently the Professor Jameson’s series of 5 books are long since out of print, and unavailable (since 1973 in the UK), and it’s indeed hard to find any remaining quality copies. However good quality copies can still be purchased at an affordable price.
Alibris is recommended as selling quality books, providing a very efficient mail order service.
