One thing that I will take from this chapter is to look for often cited authors. He says to look for authors that are used a lot and that have been cited man times. If you don't look for this than you could end up with an unreliable author. Also, if they have been cited often than that would mean that they are a professional in that field and that their sources are good. Also, to look for sites that have been around for a long time. You don't want to get a source and then have that web page disappear. You want to look for credible authors and sources for your paper. A dissapearing source would not look good. Credible authors that have been cited many times are your best bet at the best information.  I would not use sources where the author is sketchy or many not be qualified on the subject that they are wrtiting about. I will also only use sources that are relaible and that have been around for a long time.
