Solving the Library Problem
Those of us who read a lot accumulate a great deal of books (according to LibraryThing I have 438); how does one categorise and shelve them? My own system is rather esoteric (deliberately so); one man and his wife had 3,500 books and came up with a cool solution to the problem utilising off-the-shelf software, a barcode scanner, new shelving and other nifty stuff.
