Examples of source classification in various topic areas
While I (and I'm sure others) appreciate the additional edits to the section, I think it should be fairly noted that they are now different from the referenced web page and source. Some of the deletions may not be that big of a deal, I don't know, but I thought I should point that out. In the case of engineering, a building or structure is an example of a primary source. wbfergus undefinedTalk 19:13, 28 September 2007 (UTC)
