The American Journal of Archaeology, the journal of the Archaeological Institute of America, provides submission guidelines for their authors. Your profesor would like you to use the AJA guidelines (specifically this author instruction pdf) when you prepare you notes and bibliographies.
Notes. AJA does not use in-text citation, except for references to primary ancient sources. Notes should be formatted as endnotes, not footnotes; they should be numbered in one series, double-spaced on pages assembled at the end of the text. Notes must be formatted according to the guidelines given below (§4.3). Authors should make every effort to reduce lengthy, discursive notes.
Works cited/ Bibliography End with a list of all works cited, in alphabetical order by last name of first author. For further information, consult Chicago Manual of Style.
Abbreviations of journal and series titles and standard works should conform to the current list in AJA (page 17).
