Follow these guidelines when making the individual parts of your paper.
All information below comes from the GSA Publications (PDF).
The abstract should not exceed 250 words, and it should present the general content and conclusions of the paper. Do not include references, criticisms, drawings, or diagrams in the abstract.
Use the International System of units (metric) in captions, illustrations, and text. Where English measurements are necessary, follow metric with English in parentheses.
Avoid footnotes and parenthetical statements. Textual footnotes that are deemed necessary should be numbered consecutively with superscripts and also typed double-spaced.
Make captions precise and explain all symbols and abbreviations that are used. Type captions in consecutive order, double-spaced. Do not put captions and figures on the same page.
Tables should replace text, not duplicate it. They should be numbered consecutively, and each must be typed on a separate page.
Appendixes should be placed at the end of the text, before the References Cited. All appendixes should have a title (for example, APPENDIX 1. SAMPLE DESCRIPTIONS).
Identify mathematical symbols -- for example, "lower-case alpha," "upper-case beta," "vector," "zero," "oh," "one," "el." Underline all variables (except vectors) to indicate that they are to be typeset in italics. Define your use of symbols in the text the first time each appears.
Follow this format for in-text mathematical equations and expressions:
