How you know you've made the right move in starting library school:
a) you think it's hilarious when the person giving a presentation about Charles Cutter (famed author of "Rules for a Printed Dictionary Catalog") says that Cutter had a feud with Melvil Dewey, making them "kind of the Professor Xavier and Magneto of library science, but without the battle royale at the end."
b) you actually moved a book from one section to another in the Hudson Booksellers in O'Hare airport because Tamora Pierce books belong in young adult fiction or sci fi/fantasy, not adult general fiction.
