We are excited to announce that we have resolved the current back order issue related to our Core Knowledge program. New books are being reprinted and should leave the warehouse within 4 weeks. We appreciate you patience during this time and your commitment to this program. We are currently reworking our licensing agreement and "In Print" status. As final information is determined, we will update this page.
