Truthfulness of our online resources??

Regarding the article on the truth from online sources- teaching students to slow down and think more when they are reading information online is very important.  I share the author's frustration in watching students find information online and refuse to read an entire article.  They skim articles for a piece of information and move to the next resource in order to find the facts they need and nothing more.

I also see the students perspective of feeling overwhelmed by the amount of information available from the online resources.  It can be very difficult to know if a source is trust worthy or reliable, this is something that I never had to question when I used the Encyclopedia Britannica to do my research.  

I wonder if it is o.k. to limit the students sources that they are allowed to use for their research.  I may pick 5-10 online sources that I think are good and reliable and give my students the links and let them choose from within a limited number in order to help them better manage their time, because time is always an issue for a research project that will be done during school hours.
