citing sources
Why citations? Writing to create new knowledge and understanding of the world is usually not an individual effort. It is, instead, analogous to joining a conversation in which everyone learns from everyone else. Your ideas join with the ideas of others to change the contours of what is known and unknown. Joining a knowledge creation conversation in writing requires that you acknowledge and respect the ideas and work of others through citation. Readers benefit from learning who and what has informed your work. Once they see and can evaluate the arguments being advanced and the evidence that supports or weakens your work, they can prepare themselves to join the conversation to create create new knowledge themselves. Or, maybe they just want to learn as much as they can about the ideas you and others are advancing. Thoughtful and careful citations are a gift to your reader and show your gratitude to those who have helped you understand the world.

When a credible source verbally shares information
(Jose Garcia, personal communication 2021)
One source that informs an entire paragraph: Can I use one citation at the end of a multiple sentence paragraph to indicate where I've obtained most of the information in the paragraph? Short answer: NO. Read more here; this is important!
Citing a Source Cited by Another Author
When you want to use information provided by an author you are reading but that author is citing another author what do you do? You must NOT take the citation without checking the original author's work. This is how data, interpretations, arguments get distorted. In some cases (e.g., when you cannot gain access to the original source) you can signal to your reader that you are citing an author but did not check the source. This would be cited in your text as: (Johnson 2012:22 as cited by Smith 2020:19). Both the Johnson and Smith sources must be entered your References Cited list.
Headings
Headings are essential for signaling to a reader where they are in your argument and should go descriptively beyond the perfunctory Background, Methods, Results, Discussion, etc. headings. Well crafted headings should signal the primary argument or theme of the section. Following the SAA Style Guide p. 13, headings are arranged in a hierarchy:
1) Primary heads: centered, bold with headline-style capitalization. EX: Vernacular Cabins of Southern Colorado
2) Secondary heads: flush left and set in italics, using headline-style capitalization. EX: Milled Lumber as a Temporal Indicator
3) Tertiary heads: typed as part of the paragraph, with a paragraph indentation, the head italicized, with headline-style capitalization, followed by a period, and followed by the beginning of the text. EX: Sawcut vs. Milled Lumber. Sawcut wood can be differentiated...
See the Style Guide for details on spacing and other details.

Common mistakes:
- Placing a single citation at the end of a paragraph that is filled with content from one or more authors (see above; there is a method for solving this!)
- Missing page numbers. Page numbers from where, specifically, within a document you derived the information you are collecting are essential! So, all in-text citations must have page numbers.
- Missing date accessed from electronic resources/webpages
- Not knowing the difference between a "Figure" and a "Graph" - almost everything is referred to as a "Figure" -- including photos.
- putting a citation at the end of a sentence rather than when an author is first mentioned in the text. For example, "Smith describes the process of extracting water from rocks (Smith 1999:21-25). This is incorrect; instead, present the citation this way: "Smith (1999:21-25) describes the process of extracting water from rocks."
- Missing labels for the x or y axis or missing caption citations if the figure contains data from others.
- Missing the year for a citation in the "References Cited" section. See this example with a missing year:
