Especially when it comes to writing op-eds, incorporating quotations from experts can be a great way to bolster your arguments. Unfortunately, an 800-word op-ed doesn't leave much room for lengthy block quotations. So writers often shorten quotes by using ellipses. However, if you find yourself doing this, be extremely careful. When you chop up a quote, it's easy to alter the meaning completely. This can be an honest mistake or, worse, a purposeful manipulation.
To see how someone’s words can be misrepresented by an artfully placed ellipsis, look no further than a recent Amazon letter released online at ReadersUnited.com. The letter makes the argument that today's book publishers are attacking Amazon's eBooks in the same way that the literary community opposed the introduction of paperbacks, which were much cheaper than the alternative hardcovers at the time.
