What is the proper order for the end of my book, or back matter?

"Back matter" consists of the pages and materials that generally fall after the main body of the text. You can decide what to include or not include in this section of your book. Here is the general order of back matter according to the Chicago Manual of Style: 1) Appendix, 2) Notes, 3) Glossary, 4) Bibliography, 5) List of Contributors, 6) Index, 7) Author biography and/or photo.
