While trying to do our planning for 2009, I fund that the AAP's link to their State Textbook Adoption Schedule was broken.  So, I searched the internet to try and create my own from the resources of the world wide web.  Feel free to utilize the attached schedule for your own planning.  Let me know if you find any discrepancies and I will update the sheet.   I tried to use the most accurate data I could find, but there is bound to be some errors.
