Elsevier, yes the same academic publishers who were recently caught publishing fake medical journals to promote the products of paying pharmaceutical companies, has admitted to paying people to give five-star reviews to one of their textbooks on Amazon.com.

I wonder: is Elsevier the only publisher carrying out these dishonest business practices, or are they merely the only ones with the misfortune of being caught. And what are librarians doing, if anything, to make sure their trust in publishers is not misplaced?
