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 etc into single brackets like this 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 kncyu talk contribs
