Sonlight upgrades our Instructor's Guides (IGs) each year. Sometimes this involves major changes, sometimes the changes are minor, but there are always changes. Every year Sonlight must replace books that have gone out of print, or we may find a book that better fits our standards or goals for a particular curriculum. Also, because customer input is such a valuable resource for us, you will find that each new Instructor's Guide implements many suggestions we have collected from Sonlight users over the previous year. The Instructor's Guide comparison chart on our website may have some additional information for you: http://www.sonlight.com/ig-update-chart.html .
