Know which sources to acknowledge.
As you carry out research, it is important to understand the distinction between materials that require acknowledgment (in in-text citations, footnotes, or endnotes; and in the works-cited list or bibliography) and those that do not.
Materials that do not require acknowledgment
- Common knowledge. If most readers already know a fact, you probably do not need to cite a source for it. You do not need to credit a source for the statement that Barack Obama was elected in 2008, for example.
- Facts available in a wide variety of sources. If a number of encyclopedias, almanacs, or textbooks include a certain piece of information, you usually need not cite a specific source for it.
- Your own findings from field research. If you conduct observations or surveys, simply announce your findings as your own. Acknowledge people you interview as individuals rather than as part of a survey.
Materials that require acknowledgment
Some of the information you use may need to be credited to a source.
- Quotations, paraphrases, and summaries. Whenever you use another person’s words, ideas, or opinions, credit the source. Even though the wording of a paraphrase or summary is your own, you should still acknowledge the source.
- Facts not widely known or claims that are arguable. If your readers would be unlikely to know a fact, or if an author presents as fact a claim that may or may not be true, cite the source. If you are not sure whether a fact will be familiar to your readers or whether a statement is arguable, cite the source.
- Visuals from any source. Credit all visual and statistical material not derived from your own field research, even if you yourself create a graph or table from the data provided in a source.
- Help provided by others. If an instructor gave you a good idea or if friends responded to your draft or helped you conduct surveys, give credit.
