The 200 books in these two book bags are all owned by our school and can be found in the Elementary School Library.  I selected my favorite 200 out of more than a thousand which are all of a reading level between 2.0 and 4.0 (grade level).
Book Bag #1                Book Bag #2
I also highly recommend that every student own a library card for a public library (Anderson-Lee in Silver Creek, Barker in Fredonia, or Dunkirk Free Library.  There are many more books available to you (and the entire family) there.
