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.
