Excellent idea Joe
Camsco had done a great job in making unavailable books accessible.
I'm always horrified when I find how much books we paid a few pennies for now cost.
In the Sixties I started to purchase the Bronson at £10 per volume -   got as far as volume two, but couldn't afford Three because it had risen to £15.
Finally got the last two via the kind assistance of the Librarian at Cecil Sharp House - cost me £25 each
Good days!
