Sociology students and researchers must navigate a specific set of rules when documenting their sources. The American Sociological Association (ASA) style is the standard for manuscripts in the field, emphasizing clarity, precision, and a streamlined author-date system. While it shares roots with the Chicago Manual of Style, ASA has unique nuances—particularly regarding punctuation and the presentation of author names—that can make or break the professional appearance of a research paper.

This comprehensive guide breaks down every aspect of the ASA citation format, ensuring your work meets the rigorous standards of academic publishing.

Core Principles of ASA Paper Formatting

Before diving into specific citations, the overall manuscript must adhere to general formatting guidelines. Consistency in layout reflects the organizational rigor of the sociological research itself.

General Page Layout and Typography

Standard ASA style requires papers to be double-spaced throughout, including the reference list and block quotations. The preferred font is 12-point Arial or a similar legible sans-serif font, though some departments may accept Times New Roman. Margins should be set to 1.25 inches on all four sides.

The Title Page and Abstract

Every ASA-style paper begins with a separate title page. This page includes the full title of the manuscript, the names of the authors, the institutional affiliation, and a total word count (including footnotes and references). Often, a "running head" is not required unless specified by a specific journal, but a short title at the top left of each page is common.

Following the title page is the abstract—a single paragraph of roughly 150 to 200 words summarizing the research question, methodology, and key findings. The abstract should be on its own page, headed by the word "Abstract" in plain text.

Mechanics of ASA In Text Citations

The ASA style uses an author-date system. This means that every time you paraphrase a theory or quote a study, you must acknowledge the source within the text, directing the reader to the full entry in the references section at the end.

Basic In Text Citation Rules

In the most standard form, the author’s last name and the year of publication are placed in parentheses. Unlike APA style, there is no comma between the name and the year.

  • Example: The rise of digital ethnography has reshaped how we view community (Smith 2023).

If the author’s name is already part of the narrative, only the year is placed in parentheses immediately after the name.

  • Example: Smith (2023) argues that digital communities are as robust as physical ones.

Citing Multiple Authors

The rules for citing multiple authors change depending on the number of contributors and whether it is the first time the source is being mentioned.

  1. Two Authors: Always list both last names connected by "and."
    • (Jones and Miller 2021)
  2. Three Authors: List all three last names in the first citation. In subsequent citations, use the first author's last name followed by "et al."
    • First mention: (Davis, Thompson, and Garcia 2019)
    • Subsequent mentions: (Davis et al. 2019)
  3. Four or More Authors: Use the first author’s last name followed by "et al." for all citations, including the first.
    • (Williams et al. 2020)

Handling Direct Quotations and Page Numbers

When you use a direct quote or refer to a very specific passage, you must include the page number. In ASA style, the page number follows the year after a colon, with no space between the colon and the number.

  • Example: "The sociological imagination allows us to grasp history and biography" (Mills 1959:6).

If the quote is longer than 50 words, it should be formatted as a block quote: indented, single-spaced (in some variations), and without quotation marks. The citation for a block quote comes after the final period.

Special Cases in Text

  • No Date: Use "n.d." in place of the year (e.g., Johnson n.d.).
  • Multiple Works by the Same Author in the Same Year: Distinguish them with lowercase letters (e.g., Brown 2018a, 2018b).
  • Multiple Sources in One Parenthesis: List them in alphabetical order by the first author’s last name, separated by a semicolon (e.g., Adams 2015; Zola 2012).

Constructing the References List

The references list appears at the very end of the paper. It is a comprehensive list of every source cited in the text. It is not a bibliography; only works actually cited should be included.

Formatting the List

The list must be double-spaced and organized alphabetically by the first author's last name. Use a hanging indent, where the first line of each entry is flush left and subsequent lines are indented 0.5 inches.

A crucial distinction in ASA style is that authors' full first and middle names should be used whenever available. This contrasts with styles like APA, which only use initials.

Referencing Books

The general format for a book includes the Author’s Last Name, First Name. Year of Publication. Title of Book. City, State: Publisher.

  • Single Author: Welch, Kathleen E. 1999. Electric Rhetoric: Classical Rhetoric, Oralism, and a New Literacy. Cambridge, MA: MIT Press.
  • Two or More Authors: The first author’s name is inverted (Last, First), but the following authors' names are written in normal order (First Last). Lunsford, Andrea and Lisa Ede. 1990. Singular Texts/Plural Authors: Perspectives on Collaborative Writing. Carbondale, IL: Southern Illinois University Press.
  • Chapter in an Edited Volume: Wells, Ida B. 1995. "Lynch Law in All Its Phases." Pp. 80-99 in With Pen and Voice, edited by S. W. Logan. Carbondale, IL: Southern Illinois University Press.

Referencing Journal Articles

For journal articles, the article title is placed in quotation marks and uses sentence case (capitalize only the first word and proper nouns). The journal title is italicized and uses title case (capitalize all major words).

  • Print Journal: Innocente, Nathan and Jayne Baker. 2018. "The sociology teaching fellowship." Teaching Sociology 46(4):335-45.
  • Online Journal with DOI: If a DOI is available, it is always preferred over a URL. Persell, Caroline Hodges. 2008. "How sociological leaders teach." Teaching Sociology 36(2):108-24. doi:10.1177/0092055X0803600202.

Referencing Digital and Electronic Sources

In the modern research environment, many sources are exclusively online. ASA requires specific retrieval information for these.

  • Websites: Include the date the content was published or the date it was last modified. If no date is available, use "n.d." Include a retrieval date if the content is likely to change. American Sociological Association. 2024. "Ethical standards of the ASA." Washington, DC: American Sociological Association. Retrieved May 15, 2024 (https://www.asanet.org/ethics).
  • Social Media and Blogs: Treat these similarly to websites, providing the author (or handle), the date, the title of the post in quotes, and the platform name.

Advanced ASA Formatting: Headings and Visuals

To maintain organization in long manuscripts, ASA uses a specific hierarchy of headings. These help the reader navigate the transition from methodology to findings and discussion.

Heading Hierarchies

  1. Level 1 Heading: ALL CAPS, LEFT-JUSTIFIED. Do not use an "Introduction" heading at the start of the paper; the first Level 1 heading usually begins with the first main section after the intro.
  2. Level 2 Heading: Italicized, Title Case, Left-Justified.
  3. Level 3 Heading: Sentence case, italicized, indented at the start of the paragraph. These end with a period, and the text begins immediately after.

Tables and Figures

Tables and figures should be placed at the end of the manuscript, after the references list, each on a separate page. In the text, you should indicate where they belong by inserting a note: [Table 1 about here].

Each table needs a descriptive title (e.g., Table 1. Demographic Characteristics of Survey Respondents, 2023). The data within tables should be clear, and any abbreviations must be explained in a note below the table.

Common Pitfalls in ASA Formatting

Even seasoned researchers occasionally slip up when applying ASA rules. Recognizing these common errors can save significant time during the editing phase.

The Comma Confusion

The most frequent error is inserting a comma between the author and the year in an in-text citation (e.g., Smith, 2023). This is standard in APA but incorrect in ASA. Always check your parentheses for that stray comma.

Page Number Punctuation

In ASA, the colon separating the year and the page number has no space (2023:45). Many writers accidentally type "2023: 45," which is technically a violation of the style guide.

Reference List Names

Remember to use the full first names of authors. If you are citing a source where the author only used initials, you may use initials, but if the full name is known or listed, the ASA prefers it for better identification and to acknowledge the scholar's identity.

Journal vs. Article Title Case

It is easy to forget the "sentence case" rule for article titles. Most other styles use title case for everything. In ASA, only the journal name gets the full capitalization treatment; the article title should look like a standard sentence.

Why ASA Style Matters for Sociology

Adhering to a standardized format like ASA is not just about following arbitrary rules; it is about participating in a professional community. When everyone uses the same "language" for citations, the focus remains on the sociological arguments and data rather than the mechanics of the writing. It allows for seamless cross-referencing and ensures that credit is given where it is due, maintaining the integrity of the discipline.

For those transitioning from other styles, the primary adjustment is the "cleanliness" of the author-date system and the specific handling of the references list. By mastering these details, you demonstrate your competence as a researcher and ensure your work is taken seriously by peer reviewers and academic mentors.

Summary of ASA Citation Rules

Effective use of the ASA format involves three main components:

  • General Formatting: Double-spaced text, 12pt sans-serif font, and specific heading levels.
  • In-Text Citations: An author-date system without commas (e.g., Smith 2024) and page numbers following a colon (e.g., Smith 2024:12).
  • Reference List: A hanging-indented, alphabetical list providing full names for all authors, with article titles in quotes and book/journal titles in italics.

FAQ

What is the main difference between ASA and APA style?

The most significant differences are in the in-text citation and the reference list names. ASA does not use a comma between the author and the year (Smith 2023), whereas APA does (Smith, 2023). Furthermore, ASA requires full first names in the reference list, while APA uses only initials.

How do I cite a source with no author in ASA?

If a source has no author, use the name of the organization or agency that published the work. If no organization is responsible, use the first few words of the title in the in-text citation and alphabetize by the title in the references list.

Does ASA style require a DOI for online articles?

Yes, if a Digital Object Identifier (DOI) is available, ASA requires it. It should be placed at the end of the reference entry. If no DOI is available, a stable URL or a permalink from a library database should be used instead.

How should I format the "References" header?

The word "References" should be centered or left-justified at the top of the page following your main text. It is a Level 1 heading, so in a strictly formal ASA manuscript, it would be in ALL CAPS.

Can I use footnotes in ASA style?

ASA discourages the use of footnotes for citations. However, "content footnotes" can be used to provide brief explanatory information that would otherwise disrupt the flow of the text. These are indicated by superscript numbers and listed at the end of the page or in a separate section before the references.

How do I cite a work that has not yet been published?

If a work is scheduled for publication but not yet out, use the term "forthcoming" in place of the year in both the in-text citation and the reference list. If it is an unpublished manuscript that is not yet scheduled, use the term "Unpublished manuscript."
