IAP Style Guide



  • Do not use page cross-references. Instead, refer to the chapter and the heading under which the material appears, e.g., “(see Chapter 5, Health Behavior).”
  • If referencing information found elsewhere in the chapter, parenthetically refer to the heading or section under which the material appears. Do not use “above” or “below” as the APA Guide advises against it.


  • Supplementary content can be text that the author wants to highlight, additional information, or materials separate from the running text of the chapter.
  • Like tables, exhibits/boxes/cases/ etc. should be numbered consecutively within each chapter using the double-number format (chapter number/exhibit number). For example, the fourth exhibit in chapter two would be numbered “Exhibit 2.4”.
  • Cite the exhibit in text (as with figures and tables) either parenthetically or in text.
  • Group all such supplementary materials together at the end of the chapter manuscript.

Figures and Illustrations

  • Keep illustrations as simple as possible. Avoid large black areas and/or very dense patterns which do not reproduce well.
  • Ensure that all figures and illustrations serve an academic or pedagogical purpose. Decorative or unnecessary figures and illustrations should not be used.
  • All figures and illustrations will be converted to and printed in black and white.
  • Like Tables and Exhibits, Figures should be numbered consecutively (in order of appearance) within each chapter using the double-number format (chapter number/figure number). For example, the fourth figure in chapter two would be numbered “Figure 2.4.” All figures must be cited, either parenthetically or in the text.
  • Limit use of gray tones in charts or graphs. An acceptable selection of gray tones is 20%, 50%, 80%.
  • Errors in figures must be corrected by the author or editor.

Figures Submitted Electronically

  • Line art should be submitted or scanned at 600 to 1200 dots per inch (dpi).
  • Halftones (photos) should be submitted at 300 dpi and must be saved as TIF files.

Note: An easy way to check resolution of line and halftone figures is to use Microsoft Office Picture Manager. (Open the file in MS Picture Manager; right click on the image itself, select PROPERTIES, then MORE under Picture Properties. The dpi will display.)

Figures Submitted as Hard Copy

  • If an author cannot supply electronic versions of one’s figures, supply good-quality hard copies (printed at 1200 dpi on laser paper).
  • Below each figure, outside the area of the figure itself, write the figure number, author name, the volume’s title, and any notations (indicate the top of the figure if there could be doubt about its correct orientation).
  • If an author wishes to have figures returned, please alert the volume’s Editor.

Type chapter headings in a consistent style to ensure correct interpretation by the copyeditor and typesetter. All headings should be on a separate line and not run into the text.

  • Type Number 2 Heads in Bold, Italics/Title Case
  • Type number 3 heads in bold, italics/sentence style
  • Type number 4 heads in italics/sentence style

Italics and Boldface

  • New or special terms are often highlighted by italics. Boldface is reserved for headings or math vectors.
  • Once a term has been highlighted by italics, it is not to be emphasized again.

Mathematical Equations

  • All mathematical equations must be set in Math Type and NOT Word Equation editor.


  • It is the author’s responsibility to obtain any permissions required for copyrighted material reused in the book prior to delivery of the manuscript. This includes quotations of 50 words or more, illustrations, and tables that don’t fit into the categories of fair use or public domain. Song lyrics and poetry always require permission unless they are in the public domain. These can be costly and/or difficult to obtain; IAP suggests avoiding such material whenever possible.
  • Where there is any doubt, such as using a modified version of an illustration, it is wise and courteous to ask for permission and to give credit for the material (e.g., Modified from ..., Adapted from...).
  • If an author is preparing a revision, the author must reapply for permission unless the permission granted for the previous edition included “this and all subsequent editions.”
  • Be sure to include the appropriate source line as a table footnote or as part of the figure caption. Follow any specific wording requirements itemized by the original publisher.
  • Attach signed IAP Permission Request Form(s). Note: Many publishers require a photocopy of the figure/table to be reprinted to accompany the permission request (to ease locating the figure/table).
  • The permissions process can take upwards of 6 weeks, so be sure to address this requirement early in the authoring process.
    Note: Include electronic copies of IAP Permission Forms granting permission to reproduce all copyrighted material with the final version of the manuscript. (The author is to retain the original signed permission forms.) The volume will not go forward into production until these documents are secured, forwarded to, and received by the volume’s Editor.
  • The volume’s author(s) are responsible for payment of all permissions fees. If a contract stipulates an advance against royalties, this should help author pay permissions fees.


  • A direct quotation of not more than 40 words should be enclosed in quotation marks and run into the text.
  • Longer quotations—extracts—should be indented at least 5 spaces from the rest of the text from the left margin, double spaced, and without quotation marks.
  • Use ellipses (...) to indicate any point in a quote in which material has been omitted. If the omission occurs at the end of a sentence, use 4 dots, the first being the period.
  • If add italics are added for emphasis to material within the quote, indicate it with a footnote: “Italics mine.”
  • If material is added to a quotation, place it within brackets not parentheses. Parentheses should appear only as used by the original author.
  • Check each quotation to ensure it is verbatim.
  • Include the complete source of original publication in the References section the end of the chapter.


  • IAP requires the Publication Manual of the American Psychological Association, 7th Edition.
  • A reference is a source tha cited in the text. If the source is not cited in the text, it should be placed in a section of “Additional Readings.” These sources should be unnumbered and typed in alphabetical order by author.

NOTE: Do not use the automatic reference feature in Word or reference tools like EndNotes®; these are not compatible with IAP’s typesetting systems.


  • Use tables when content can be more effectively presented in this format, especially when comparisons are intended.
  • Presentation of tables should be as simple as possible. A long table with few columns is preferred to a wider table with many columns.
  • Feel free to use horizontal and vertical rules to clarify alignment for our copyeditors and typesetters. (These rules will not necessarily appear in the printed book.)
  • A summary of the findings in a table should be discussed in the text. Always cite tables formally in text using the double-number system (chapter and table number; e.g., see Table 12.1) not “see table below.” Double-number tables consecutively within each chapter (e.g., the fourth table in chapter two would be numbered “Table 2.4”).
  • Always double-check tables for accuracy, recalculate any totals, and proofread them carefully.
  • Group all tables together at the end of the chapter manuscript.

Units and Abbreviations

  • Always leave a space between a number and a unit, e.g., 5 mm. Use abbreviations that are accepted nomenclature and use them consistently.
  • Define all abbreviations and acronyms at the first point of use, e.g., cyclic adenosine monophosphate (cAMP). Spell out acronyms on first usage.
  • After the first use, the acronym must be used an additional 4 times.
  • Once an acronym has been introduced, do not alternate between the full term and the acronym. The acronym is to be used exclusively for the rest of the chapter.
