Book 'em

Books at my library are often mis-shelved. Not only is the cataloguing system all caddywampus due to the high turnover of librarians, but many of my users just can't be arsed to put things back where they found them (or even in the reshelving area). What's pictured here is not a particularly egregious example, but, whoa, Nelly there have been some doozies. Many a student has come a'looking for something which is somewhere in the library, but will not turn up for a good long while.
