"The distinction between types of sources can get tricky, because a secondary source may also be a primary source. Garry Wills' book about Lincoln's Gettysburg Address, for example, can looked at as both a secondary and a primary source. The distinction may depend on how you are using the source and the nature of your research. If you are researching Abraham Lincoln, the book would be a secondary source because WIlls is offering his opinions about Lincoln and the Gettysburg Address. If your assignment is to write a book review of Lincoln at Gettysburg, the book becomes a primary source, because you are commenting, evaluating, and discussing Garry Wills' ideas."
Fortunately, Wikipedia did not exist in 1863. Had you been at Gettysburg then and writing about it, NOR would have prevented America from ever hearing about Lincoln's speech. :-)
