- Place footnotes just below the table, designated by lowercase letters a, b, c, etc.
- Within the text, refer to table 1, table 2, etc. (using lowercase letters and numerals).
- Use horizontal rules sparingly; avoid vertical rules unless required for clarity.
- NCSU has an excellent resource on creating tables.

- Use the References to list more details of the website, when necessary (see the section on references below).
- Use end punctuation if the website address falls at the end of a sentence.
Short communications and technical notes are typically between 3,000 to 4,000 words including abstract, captions, and references. Long form research articles, studies, review articles, and essays should be about 8,000 words, though word limits are not enforces except for special issues.

Documentation: Author-Date System
The Author-Date System briefly cites sources in the text, usually in parentheses, by author’s last name and date of publication. These short citations are detailed in References at the end of the paper. What follows is a description of the citation style to be used in the JAIC. For more complete details, refer to the Chicago Manual of Style, 16th edition, or download the Taylor and Francis guide.
- To a reference as a whole:
(Smith 1999, 2002)
(Thomson 1987; Jones 1999; Smith 1999) -- list multiple sources chronologically
(Pratt 1992a, b)
(Singh and Butcher 1990)
(Tucci  1988)
- To a specific page in reference:
(Smith 1999, 49)
Include page numbers in text citations only when meaningful: with direct quotations, or when paraphrasing from a long work in which the concept is not immediately accessible to the reader. Do not use page numbers in references to a journal article or short manual except to support a direct quote.
- Place after author’s name, if possible: Learner (1996) used PyGC-MS to look at a number of synthetic organic pigments.
- If the author and date are in the text, only the page number is needed: In 1906, Forster (54) said, “A critic has no right to the narrowness which is the frequent prerogative of the creative artist.”
- For four or more authors, use first author’s last name and et al.:
incorrect = (Florian, Kronkright, Swift, and Norton 1992)
correct = (Florian et al. 1992)
- If References includes two works of the same year by one author with different coauthors, distinguish them by the second author’s name: (Smith, Jones et al. 2000; Smith, White et al. 2000).
- For authors’ names, provide full names.
- List all authors; do not use et al. in References.
- Italicize (do not underline) titles of books and names of journals.
- Use headline-style capitalization for article names and book titles. In headline style, the first and last words of title and subtitle and all other major words (nouns, pronouns, verbs, adjectives, adverbs) are capitalized. For non-English titles, use sentence-style capitalization.
- Convert Roman numerals to Arabic for volume numbers.
- Spell out the title of the journal and give both volume and page numbers; include issue number, month, or season only when pagination is not continuous through the volume.
- Arrange entries alphabetically by author’s last name; place Mc after Mb and before Md.
- For more than one entry by the same author(s), arrange by date, earliest to latest;
- For more than one entry by same author(s) in the same year, arrange in alphabetical order by title and label a, b, etc., after the year (e.g., 1992a, 1992b, etc.)
- Place author’s own volume before a book s/he edited.
- Place single-author entries before multiple-author entries.
- Arrange entries with the same first author and various multiple authors according to the last name of the second author, not by the number of authors.
- Alphabetize corporate authors (such as associations) according to the first significant word or acronym.
- For place of publication, list only the first city; for Canadian publications, provide province and Canada.
- If there are references not cited in the text, group them after References under Further Reading.
- All URLs in References should have the prefix http:// or https:// and include a final / wherever they appear.
- If it is necessary to use a URL in the text, use the full prefix and include any final /.
- When one is available, list a Digital Object Identifier (DOI) rather than a URL.
- Only include access dates if there is no date of publication or date of last update. Place the date last accessed in conventional form (e.g., August 4, 2014) before a URL or DOI.
- Cyclododecane. 2014. CAMEO (Conservation and Art Materials Encyclopedia Online). Museum of Fine Arts, Boston. Accessed September 7, 2014. http://cameo.mfa.org/wiki/Cyclododecane.
Citing Online Resources in Print Publications (e.g., print editions of JAIC, BPG Annual)
- It is only necessary to cite a URL or DOI when the publication only exists online or would be otherwise difficult to locate.
- When a URL must be broken over a line in printed works, it should be broken before rather than after a slash (/).
Citing Online Resources in Electronic Publications (e.g., the Specialty Group wikis)
- Whenever possible, cite a URL or DOI when the publication exists online, and include a hyperlink to the electronic resource.
