I KEEP ALL of my movie reference books. But as far as novels or even biographies; I can get them through inter-library loan. The only book I've ever had trouble getting this way was- "Memoirs Of A Professional Cad" by George Sanders. But even that one, if I so desired, could have been mimeographed for me through the University Library. It's funny though, because about 10 years back I was able to get that book through the loan process...and through my local library too!
