Eamon Fulcher, A Guide to Coursework in Psychology (2005). See the observations below.


A collection of supplementary materials, usually appearing at the end of a report, proposal, or book. Plural: appendixes or appendices.

An appendix typically includes data and supporting documents used by the writer to develop the report. Though such information should be of potential use to the reader (not treated as an opportunity for padding), it would disrupt the flow of the argument if included in the main body of the text.


From the Latin, "hang upon"


  • "A final, optional component is an appendix. Appendices allow you to include any additional information (survey results, tables, figures, previous report findings, relevant letters or memos, etc.) that you have not built into your proposal's main text.

    "The contents of your proposal should not be of primary importance. Any truly important information should be incorporated within the proposal's main text. Valuable data (proof, substantiation, or information that clarifies a point) should appear in the text where it is easily accessible. Information provided within an appendix is buried, simply because of its placement at the end of the report. You don't want to bury key ideas. An appendix is a perfect place to file nonessential data that provides documentation for future reference." (Sharon Gerson and Steven Gerson, Technical Writing: Process and Product. Pearson, 2006)

    More Examples of Supporting Materials

    • "An appendix contains supporting materials for the report--tables and charts too long to include in the discussion, sample questionnaires, budgets and cost estimates, correspondence about the preparation of the report, case histories, transcripts of telephone conversations." (Philip C. Kolin, Successful Writing at Work. Houghton Mifflin, 2007)

      Connections Between the Appendix and the Main Text

      • "An important rule to use when including material in an appendix is: do not let information in the appendix 'speak for itself'--this means that you must not put vital information only in an appendix without any indication in the main text that it is there." (Eamon Fulcher, A Guide to Coursework in Psychology. Psychology Press, 2005)

      Appendix Format Conventions

      • "Appendix format conventions are as follows: Each table, chart, or other type of information should appear as a separate appendix, numbered and titled, on a separate page. Page numbering for the report proper should continue through the appendixes. If the report has a table of contents, the appendixes should be included in it." (Geraldine E. Hynes, Managerial Communication: Strategies and Applications, 6th ed. SAGE, 2016)
