Quoting Unique or Striking Material
Quoting unique or striking material preserves the freshness, power and beauty of the author's original words. Paraphrasing or summarizing this kind of material will diminish the inherent strength that attracted you to them in the first place.
Direct quotations allow you to "borrow" the writing tone and style of a recognized author. This will enhance your own writing, without plagiarizing, and make it more appealing to your reader while successfully conveying your own ideas.
