Give each item its own appendix. If you have two graphs, a photograph and an explanation of a formula, for example, each should have its own appendix.
Label each appendix, such as "Appendix A," "Appendix B," "Appendix C," "Appendix D," without quotations in the order they appear in the paper. If you have only one item, label it "Appendix."
Center the appendix label at the top of the page. Drop down two lines to begin the first appendix entry.
Write a short introduction to each appendix to explain the purpose of the material, since it is given out of the context of the actual paper.
Include a short conclusion at the end of each individual appendix, explaining the implications of the information provided or any relevant clarification you feel is necessary.
