This is a great site if you're looking to find out of print stuff! Some people are even selling stuff for normal prices! A copy of "Neil Campbell Kneale" is on the way and I am happy. Anyone else use it? You can look at the bit of my 'collection' I could be bothered to put on over the last few days here

It could be somewhat geeky and time consuming if you wanted it to be, but it gets results I guess
