A tip: How to trust the internet information?

There is a tip for us to filter the information on internet and then trust it. That is to look into the author of the article or website.

For example, the aticle about information literacy in the website of http://www.libraryinstruction.com/infolit.html which I recommend to you was written by Barbara Humes. When I googled her,there is a link about this person at http://catalogue.nla.gov.au/Record/4151502. From there, I knew her book was collected and made into microform in Educational Resources Information Center at Washington DC.

I did another googling for the website author,Michael Lorenzen. Here is the link for him at http://library.cmich.edu/bibliographers/michaellorenzen/. The webpage told me that he is the head of reference services/bibliographer for Philosophy and Educational Administration in Central Michigan University.

From the above searching and finding, I believe Babara's article and Michael's website are reliable sources for my research beause both of them are professional in this field.
