(7.4) Illustrations, especially graphs and charts, should be placed as close as possible to their first reference in the text. They should be referred to by number so their exact placement is flexible (see 6.13 ? 6.17).

(7.13) Even if a paper contains several types of illustrations, such as maps, charts, diagrams, and graphs, it is desirable to label them all as figures and to number them consecutively, using arabic numerals:

Figure 1   Figure 2   Figure 3   Figure 4

(7.14) A legend follows the figure number; this may be only a title or a caption:

Figure 2. Block diagram of Garden of the Gods

Note: Often the legend consists of a sentence or more (not necessarily grammatically complete) of explanation. In this case, the punctuation and capitalization follow ordinary sentence style:

Figure 9. Relation between number of buds or leaf scars, number of branches subsequently produced, and length of shoots. Small numbers identify multiple observations of same value.

(7.15) The legend (caption) should be single-spaced and may run the width of the illustration. Short legends (captions) are centered.

(7.18) A brief statement of the source of the illustration is usually necessary or appropriate. The only significant exception is an illustration created by the author of the paper. The credit line immediately follows the legend (caption) and is listed after the word Source: (in italics), followed by a colon and two spaces. The source material beneath the illustration should be in the same format as it is listed in the reference list (RL) source that is in the Works Cited.

(6.58) Legends (captions) and sources are typed flush on the left margin with one blank line space between the illustration legend (caption) and the source or note. Double-space between items, single-space within items. Leave three blank line spaces after the source or note and before the continuation of the text following an illustration (i.e., the text is typed on the fourth line following the last caption (legend, source, or note) beneath an illustration).

(1.19) Following the table of contents (labeled simply CONTENTS), the list of illustrations (entitled simply ILLUSTRATIONS), is given on a separate page. The figure numbers are given in arabic numerals followed by a period; the figure numbers are aligned on their periods under the word Figure, and the captions begin two spaces after the period following the figure number. The page numbers (in arabic numerals) are separated from the legend (caption) by dot leaders, and are listed flush at the right margin under the word Page (see 1.20 and 14.21).

(1.21) Figures must not be numbered 1a, 1b, and so forth. A figure may have lettered parts to which its legend or descriptive statement (caption) refers; however, do not include the lettered parts in the list of illustrations:

Figure 1. Digitalis: a, stem cross section; b, enlargement of a seed (caption below figure)

Figure 1. Digitalis (caption in list of illustrations)

(1.22) The legends (captions) in the list of illustrations should agree with those given beneath the illustrations, unless they are long, in which case it is best to shorten them in the list of illustrations.

(1.23) In the list of illustrations, legends (captions) are capitalized headline style (see 4.6 - 4.8 and 14.21).

Tables

(6.1) Tables efficiently organize and compress data into a standardized form.

(6.13) Every table should be numbered with an arabic numeral and given a title, even though there may be few tables in the paper. The order in which the tables are mentioned in the text determines the numbering, which continues straight through all chapters or parts of a paper.

(6.14) Tables in an appendix should be numbered separately from the tables in the text as A1 (Appendix One), A2 (Appendix Two), and so on.

(6.15) All text references to a table should be by number, not by an introductory phrase such as "in the following table." Numbered references to tables make it possible to set the table at the end of the page or the paragraph, or on a separate page (see 6.17). The reference may be in running text or in parentheses (see 6.16):

The percentages in table 5 illustrates this margin of error.

A majority of voters were absent during the election (see table 4).

(6.19) If a table appears on a text page, three blank line spaces should be left above the table number and table title (i.e., the table number and title is typed on the fourth line following the preceding text (see 14.31). If a table appears on a text page, three blank line spaces should be left below the table source and/or notes (i.e., the text is continued on the fourth line below the table's source and/or notes) (see 14.31).

(6.26) Each numbered table must have a title. Place the table number above the table at the left margin; add a period and two spaces, and continue with the title, running the first line and succeeding full lines the width of the table, single-spaced, and centering the last, shortest line. The title may be capitalized either headline style (see 4.6 - 4.8) or sentence style (see 4.9). Use one style of capitalization consistently in table titles throughout the paper:

Table 21. Probable rate of damage per foot-candle for thirty light sources expressed in percentage relative to zenith day

(6.51) If data for a table are not the writer's own, but are taken from another source, a source note should be included; it is placed flush on the left margin and is introduced by the word Source: (in italics) followed by a colon and two spaces. The source material should be in the same format as it is in the reference list (RL) source that is listed in the Works Cited:

Source: Peterson, James. 1991. The world beyond Earth. Chicago, IL:     University of Chicago Press.

(6.52) Other unnumbered notes, applying to the table as a whole, follow the source; they are placed flush on the left margin and are introduced by the word Note: (in italics) followed by a colon and two spaces. Notes might include remarks on the reliability of the data presented or on how the data were collected, etc:

Note: Since data were not available for all items on all individuals, there is some disparity in the totals.

(1.24) Following the list of illustrations (labeled simply ILLUSTRATIONS), the list of tables (entitled simply TABLES) is given on a separate page. The table numbers are given in arabic numerals followed by a period; the table numbers are aligned on their periods under the word Table, and the table titles begin two spaces after the period following the table number. The table titles should agree exactly with the titles above the tables themselves. The page numbers are listed flush with the right margin under the word Page (see 14.22). The titles are capitalized either sentence style or headline style (see 4.6 - 4.9), and run-over lines are indented three spaces. Double-space between items, single-space within items (see 14.22).
