Q. When including tables of statistics in an essay, do I place all the tables in one appendix or each table into a separate appendix? Is the appendix before or after the bibliography? Are there any conventions when using an appendix?
A. Please see CMOS 1.59: “Appendixes usually follow the last book chapter, though an appendix may be included at the end of a chapter (introduced by an A-level subhead) if what it contains is essential to understanding the chapter.” It’s your choice whether to have a single appendix that contains all the tables or to put each table in a separate appendix. If you can’t think of any reason why it will matter to readers, then it probably doesn’t.
