Really, so does the clerk at Borders know how to use the Periodic Guide to find the most recent article on the moral questions involved in gene splicing?
Sorry clerks at Borders do what the low end aids (minimum wage workers) do in libraries, they don't even come close to the skill set of a librarian.
For one thing, I knew how to use the periodic guide in 6th grade. For another, does one need a masters in library science to know how to do this? Couldn't the clerk from borders just get a few hours of training on the Periodic Guide?
