Is the information provided specific? all information should be verifiable. Are conclusions based on research or actual figures that can be checked in other sources?
Is there any advertising or solicitation for donations associated with the source? This  financial support may skew the subject coverage by the publication. Does the author provide more than one point of view? Does the writing use inflammatory or biased language?
Currency is important in the sciences where new developments occur frequently. A study written years ago may be essential to understanding. Consider whether or not the timeliness of the information will affect its usefulness. Date is given. Check when the research was actually conducted.
Does the information source leave questions unanswered (ask the "five W's and H" to check: who, what, when, where, why and how)?
