A few books on the shelves are really great. And then there are a whole lot of books that fit nicely into this category: This has been on the shelf and in our warehouse for several years and we can't sell it; can you? You know the ones, right? The Book 4 in a six-book series. The one written by a famous person who is not a writer. Anything with (bless their hearts) Troy and Gabriella on the cover.
If we could request, I'd fill the shelves with quality. Funny books (all Mo, all the time, and I'm diving headfirst into the Campfire Weenies, and loving it) and historical books (anything by Karen Cushman) and multi-cultural books (Christopher Paul Curtis, anyone?) and serious books (why does Scholastic not sell The Book Thief?). I'd give the kids anything and everything by Kate DiCamillo (my favorite for true diversity - she can do it all, I'm convinced). I'd bring out the classics (Roald Dahl in all his glory, Dr. Seuss, Noel Streatfeild, Kevin Henkes, Beverly Cleary and beyond).
What would you want to see at your kids' book fair? (I have an entirely different list for what I'd expect at Jr. High and High School. 'Nother Post.)
