Maybe, but see #65.
The reason behind the rule against outside materials is that juries are to base their decision solely on the evidence presented in court, evidence available to both sides, and ruled admissable by the judge. If this rule did not exist, juries could basically play attorney and introduce their own evidence apart from the real attorneys and apart from the rules of evidence and apart from the scrutiny of the judge. That would be a recipe for chaos, e.g., "Your honor, we the jury find the defendant guilty based on an article we read in the Weekly World News."
