Le BMJ du 14 juillet 2009 nous relate les excuses d'Elsevier sur des pratiques anormales : un département marketing de cet éditeur proposait à des auteurs et contributeurs de publier un avis sur le livre 'Clinical psychology'
"Now that the book is published, we need your help to get some 5 star reviews posted to both Amazon and Barnes & Noble to help support and promote it. As you know, these online reviews are extremely persuasive when customers are considering a purchase. For your time, we would like to compensate you with a copy of the book under review as well as a $25 Amazon gift card.
"If you have colleagues or students who would be willing to post positive reviews, please feel free to forward this e-mail to them to participate. We share the common goal of wanting Clinical Psychology to sell and succeed. The tactics defined above have proven to dramatically increase exposure and boost sales. I hope we can work together to make a strong and profitable impact through our online bookselling channels."
