Quoting, Summarizing, and Paraphrasing

Three common techniques used to work other people's words and ideas into your writing are quoting, paraphrasing and summarizing. What are they, specifically?

Quoting:

Using the author's exact words. Always cite it and use "quotation marks."

Summarizing:

Condensing the author's words or ideas without altering the meaning or providing interpretation - you use your own words for this. Basically, presenting the original information in a nutshell. Always cite it.

Paraphrasing:

Restating, in your own words, the author's words or ideas without altering the meaning or providing interpretation. Paraphrases are about the same length as the original. Always cite it.
