What is the best site for help with leveling books for a classroom library?

I am trying to start a reader's workshop in my 3rd grade classroom. I'm having trouble finding websites that have complete lists to help me level my books. Any suggestions?

Reply:Are you refering to the Guided Reading Levels? If so this is a great web site. When I was teaching our PTA purchased a membership for each teacher in our school at a discounted rate. You can do it as an individual also. It will give you the levels for books .

Books are leveled differently according to which system you may use. For instance there's the Heineman system, ( Irene Fountas and Gay Su Pinnell), which you can get info about at the link below.

This link will enable you to view many titles of children's books and their levels according to different publishers.
