@Strongsilence-CPA  Do you realize how much carbon fuel has to be burned to produce the energy needed to recycle all that paper?  But the online community will little note nor long remember my views on Internet research, which I post mostly to reassure others that they are not missing much if they don't spend their money on the gutta percha of information delivery systems.  Where newspaper and magazine publishing has gone, the textbooks and reference books are following without my help.
