My wife and I are currently planning on moving from London, England, to Sweden. To that effect, much of the contents of our home is already in storage, and most of this is books. We sent 86 tea chests full of books to the warehouse, and we still have plenty more to go.
Many people really like our books, many people like to borrow them, and for many reasons it would be quite cool to be able to put the details of books we have into an RSS feed. When we unpack the books, we will most likely scan their barcodes and order our library (we’re geeky like that), so we will have all sorts of data available.
