Oh absolutely! I own at least one copy, and usually multiple copies, of everything Pratchett ever published, ranging from a first edition of The Carpet People through to all of the Discworld Collector's Library hardbacks that have been produced so far, and even all of his collaborative works like The Long Earth series and Good Omens et al. Collecting Pratchett's books is probably the nearest thing I have to a drug addiction.
