allibris and oclc, sitting in a tree….

Strange little bit of news that came to me via the “copy and paste a press release into my mailto form” Allibris will be offering books for sale via OCLC’s WorldCat so librarians can buy a book instead of ILLing it. OCLC will bill you, making it even stupidly simpler. No postage, no mailing & return envelopes, no messy labelling. Is this the future of interlibrary loan? Is it really cheaper to buy the book than ILL it?
