I'm sure a friend of mine told me about an online service that allows you to find out which British libraries hold the books you are after. Was this just something my research addled mind created? It wouldnt be the first time...

Thanks for any help.

No, it's not a dream. It's real. It's called COPAC. I use it all the time, it's great. But annoying that my library doesn't have half the stuff I need.

Brilliant! Thanks!
