I'm pretty sure that the University of Cambridge library will have
these - it's a copyright library and I think has all books
published in the UK. Their catalogue is online (telnet to
UL.cam.ac.uk if you want to have a go yourself). Both books are listed,
but I'm not very practised with Trumpet Telnet, and was not able
to copy or print the information. Indeed, the UK publisher is
listed as Sherborne: Alphabooks (I'm not sure what the Sherborne
bit means, unless it's a place). I doubt that the books will be
borrowable.
