Sure, number of books, well I'm currently cataloguing them, so can't be precise, but we are talking about 1500-1700. And have spent way to much on them, especially as Fred said, I'm 19. Those darn limited editions! I haven't got any extremely rare things, probably most valuable thing is the Croombie cricket cartoons, the original book from 1906. Have a couple of Rosenwater's publications, um, Chirs Saunders 2 latest big publications (the Britcher and Dennison things), oh and Captain in the Crowd, got the limited edition version of that.
One thing that is quite nice if you can get your hands on it is Goldman's Bibliography, if only to see the odd way the book is bound.
Suffice to say I have too many bloody books!
