I saw the latter, of course. It wasn't directly aimed at you, but I didn't like it, either. Um.. you know what a diff is, do you? Just in case: You can get one by looking at the history of any page, selecting two versions, and then pressing the "Compare selected versions" button. You can include it by putting the complete link (with http:// etc) into single brackets like this: [http://en.wikipedia.org/w/example_diff], the result will then appear like  this, or like this. Look at the markup, you'll figure out the rest. These diffs or differences are often used as proof of precisely which edit by another user you are talking about. That's one beautiful thing about a wiki: It doesn't forget anything, which means that people have to think before they press "Save page". Alright, enough explained. Again, can you provide any diffs?
Regarding truth, you may want to take a look at WP:A (especially this section, by the way). You see, Wikipedia has a set of guidelines and policies. Attribution, not truth, is the aim. I certainly appreciate that you care about Wikipedia like most of us do, but it's all about working together, not against each other. I'm sure that if you come up with serious doubts as to the accuracy/appropriateness of the way the book is quoted, others will listen. —KNcyu38 (talk • contribs)
