• Directly Quoting:  Must be identical to the original, using a narrow segment of the source. They must match the source document word for word and must be attributed to the original author.
• Paraphrasing::  Involves putting a passage from source material into your own words. A paraphrase must also be attributed to the original source. Paraphrased material is usually shorter than the original passage, taking a somewhat broader segment of the source and condensing it slightly.

• Summarizing:  Similar to paraphrasing, summarizing involves using your own words and writing style to express another author's ideas. Unlike the paraphrase, which presents important details, the summary presents only the most important ideas of the passage.
