Our Librarian was recently diagnosed with Lupus, so to reduce the constant barrage of germs on all the books, the Librarian bought every classroom Clorox Wipes.  Each classroom, prior to going to the Library, wiped down all their books that they were returning, and continue to do so the rest of this year!  All the library tables were wiped down as well.  I think this has also reduced the number of head colds/flu this year in the children!!
