Supreme Court Justices Using CJS or ALR?

John Shafer alluded (some time ago) on USF’s Law Library blog to Justice Kennedy stating, during an oral argument, that he would “look in Corpus Juris Secundum or ALR or something” to investigate a licensing issue.

Jason Wilson has written that the major publishers, having created and written some of the great common law and practice treatises, essentially abandoned (or were divested of?) their role as advisers to the bench and bar.

Are these publications still being written with the judiciary in mind or is Wilson correct?
