The smallest permissible type size is 9 point. Larger type sizes have correspondingly larger spacing. Authors' names and affiliations should appear below the title, centered across the page. Sub headings appear in mixed upper and lower case, boldface or underlined, and beginning at the left margin of the column. Sub-sub headings appear in mixed case, italics or underlined, indented like a paragraph, and on a separate line.
References appear at the end of the manuscript, numbered in alphabetic order.
Illustrations must appear within the margins stated above, have numbered captions, and preferably be positioned at the tops of the columns. Illustrations may span both columns. Electronic manuscript submission is preferred. However, paper manuscript submission is recommended as a backup for all manuscripts, in the event that the electronic copy is unreadable or corrupted. Please check the submission procedures again, prior to submission, for any last minute updates.
