You will use the author-date citation form adopted by the Professional Geographer and the Annals of the Association of American Geographers for all work submitted. The style is that of The Chicago Manual of Style, 14th edition, Chapter 16, style B. Do not use numbered footnotes for citations. All works citied in a paper should be listed in the bibliography alphabetically by author (multiple works by the same author are listed chronologically). Although Style B often uses initials for an author's given name, you should spell out the name. The bibliography is to be typed, double-spaced, and should include the author's last and first names.


Up to three authors. Do not separate the name and date by a comma. When including a specific page in the citation, it follows the date, preceded by a comma.

   (Short and Kim 1999, 128)
   (Dempsey, Goetz, and Szliowicz 1997)

More than three authors. Use the name of the first author followed by "et al." Note the period after al.

Two or more references by the same author. Cite by date only and separate using commas.

(Payne-Maxie Consultants 1980a, 1980b, 1980c)

Author of a chapter in an edited book. If the author of a book chapter is known, cite the chapter author(s), not the editor(s) of the book.

ABBREVIATIONS. When using i.e. (an abbreviation for id est, "that is") or e.g. (an abbreviation for exempli gratia, "for example") in a sentence, always follow the abbreviation with a comma. The common abbreviations etc., e.g., and i.e. are used almost exclusively in parenthetical references.

   All urban land is affected to varying degrees by business cycles and land
   ownership (e.g., numbers of owners, type of land).

   Most of the zoning changed from a more restrictive use to less-restrictive,
   higher-intensity uses (i.e., permissible building heights were increased and
   commercial zoning replaced residential zoning).

TABLES AND FIGURES . Abbreviate"figure" with "Fig." (e.g., Fig. 1. Metropolitan evolution as a response to transportation innovations) when a caption or legend follows. If no captions or legends are used with figures, spell out the label (e.g., Figure 1). Every table is to be numbered and is cited in the text by that number. Do not reference using "Figure 1 shows …" or "Table 3 proves …" When referencing, remember to capitalize Table or Figure.

   For the portion of the corridor inward of I-225, at no time were densities high
   enough to accept the research hypothesis (Table 19).

   As with the I-225 corridor, the C-470 corridor includes land within one mile of the
   route (Figure 3).
