I'm guessing I don't need to tell you that Dewey had pretty much gone out the window.
The district librarian and I are located in a different building, so when I went over to this library to do my end of the year report, I ended up saying some very bad words. I said them alone, because that's the proper thing to do, but I said them loudly.
And then I proceeded to fix it.
First - discarding. This library hadn't been properly weeded in years. I ended up getting rid of about 3000 books that were beyond salvaging. Torn books, books whose spines were completely broken, and some books that were actually growing mold. Don't worry - these weren't dumpster fodder. These 3000 books went home with the children who picked them off the free book table. Even if they only had one more read left in them, they got the chance to prove it.
Second - re-cataloging. Hundreds of books were quite simply, nowhere near the places they needed to be. For example Attack of the Alien Fire Ants was in non-fiction. No idea what happened there.
Third - genre labeling. As many picture books as possible were put into categories - dinosaurs, dogs, holidays, etc - so that the little kids could actually find books that interested them, rather than rummaging through a colossal mess and hoping they hit something good in their allotted library time.
Fourth - putting all that crap back. Yep. This place was such a wreck that the best solution was to empty every single shelf and start from scratch. Obviously this was done one section at a time, but I made a HUGE mess before things got better.
And lastly - I showed administration these pictures and explained that a library needs to be maintained, not just manned. And they listened. Even though we don't have a librarian in that building full time, we do have a staff member assigned there specifically for shelving and item maintenance, and teachers are handling the checkout process for their own classes -- which is a lot easier now that they can find books on their own. Ahem.
