We have created links to Powells.com and Amazon.com. We are a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for us to earn fees by linking to Amazon.com and affiliated sites. Our hope is that, with this system, teachers and families can work together to find affordable copies of recommended and required books. Many classes do not require the purchase of books. If a course is not listed, assume that there are no book purchases required at this time. Occasionally, a teacher will add a book or books to be purchased later in the year, while we hope to keep that number to a minimum, we will work to communicate well in advance, for example, of any second semester orders or additions. Each subject area has its own tab, with grade levels and classes found on each subject page.
