The Kaplan Anatomy Coloring Book, 9th Edition, is the most current book, published in 2023.  When the Advanced Biology 2nd edition textbook was first published, Apologia used the Kaplan Anatomy Coloring Book, 4th Edition, as referenced in the Coloring Book Exercises. Kaplan has subsequently changed the pagination of the 6th-9th edition coloring books. They are still 100% compatible with our Advanced Biology curriculum, but the page numbers listed in the textbook will not completely match now. We have provided compatibility charts for your convenience so your student will know which pages to color.
