Publication in Smithsonian Annals of Flight

Manuscript for serial publications are accepted by the Smithsonian Institution Press, subject to substantive review, only through departments of the various Smithsonian museums. Non-Smithsonian authors should address inquiries to the appropriate department. If submission is invited, the following format requirements of the Press will govern the preparation of copy.

Copy must be typewritten, double-spaced, on one side of standard white bond paper, with 1-1/2" top and left margins, submitted in ribbon copy with a carbon or duplicate, and accompanied by the original artwork. Duplicate copies of all material, including illustrations, should be retained by the author. There may be several paragraphs to a page, but each page should begin with a new paragraph. Number all pages consecutively, including title page, abstract, text, literature cited, legends, and tables. A manuscript should consist of at least thirty pages, including typescript and illustrations.

The title should be complete and clear for easy indexing by abstracting services. Include an abstract as an introductory part of the text, followed by an identification of the author that includes his professional mailing address. A table of contents is optional. An index, if required, may be supplied by the author when he returns page proof.

Headings are to be used discriminately and must be typed with extra space above and below.

For matters of general style (including bibliography and footnotes or notes) follow A Manual of Style, 12th edition, University of Chicago Press, 1969. For more detailed treatment on footnotes and bibliography see Citation Style Manual prepared for MHT publications (October 1963). Use the modern order of citing dates: 29 February 1972.

Simple tabulations in the text (e.g., columns of data) may carry headings or not, but they should not contain rules. Formal tables must be submitted as pages separate from the text, and each table, no matter how large, should be pasted up as a single sheet of copy.

Use the metric system instead of (or in addition to) the English system.

Illustrations (line drawings, maps, photographs, shaded drawings) can be intermixed throughout the printed text. They must be clearly numbered in sequence, as they are to appear in the text. They will be termed Figures and should be numbered consecutively; if a group of figures is treated as a single figure, however, the individual components should be indicated by lowercase italic letters on the illustration, in the legend, and in text references: "Figure 9b." Type (double spaced) all legends on a page or pages separate from the text and not attached to the artwork.

In the bibliography spell out book, journal, and article titles, using initial caps with all words except minor terms such as "and, of, the." (For capitalization of foreign language titles, follow the national practice of the language.) Underscore (for italics) book and journal titles. Use the parentheses-colon system: 10(2):5-9 for volume, number, and page citations.

Notes and footnotes, accompanying a manuscript, are to be typed consecutively, double-spaced, and on sheets separate from the text. In typing the notes the number should be typed on the line and followed by a period. The footnote number should be typed slightly above the line and should follow any punctuation mark except a dash.

For free copies of his own paper, a Smithsonian author should indicate his requirements on "Form 36" (submitted to the Press with the manuscript). A non-Smithsonian author will receive fifty free copies; order forms for quantities above this amount with instructions for payment will be supplied when page proof is forwarded.
