Who do you trust? Why, your local public library, of course. We'd never deliberately lie to you or give you false information.

Seriously, any source is only as good as the data in it. One of the six problems with the World Wide Web is that the data can be deliberately or unknowingly inaccurate.

The more information that is available to you the more it becomes YOUR responsibility to verify the accuracy of the information. That means comparing it to other sources of the same information, going back to the original doccuments, finding out what has developed since the original was published, and, in general, a LOT of work.

But what the hey! Ultimately, it's only your own survival....
