This is logical and something that many have suspected, but there’s nothing like data…

Thanks to Fred Stoss for sending the link to multiple lists, after it was written up in The Chronicle of Higher Education today.

One answer: good scholars should have the discipline to go beyond the most convenient information sources. Another answer: bring everything into the electronic fold. I suspect that it’s the second course of action that will continue to be pursued; then, before long, it will be advertised as a completed job.
