We really need a plagiarism detection tool so that we can make sure our sources are not simply "copy and pastes" of older versions of Wikipedia. Today I was happily improving our article on pneumonia as I have a day off. I came across a recommendation that baby's should be suction at birth to decrease their risk of pneumonia with a {{cn}} tag. So I went to Google books and up came a book that supported it perfectly. And than I noticed that this book supported the previous and next few sentences as well. It also supported a number of other sections we had in the article but was missing our references. The book was selling for $340 a copy. Our articles have improved a great deal since 2007 and yet school are buying copy edited version of Wikipedia from 5 years ago. The bit about suctioning babies at birth is was wrong and I have corrected it. I think we need to get this news out. Support Wikipedia and use the latest version online!
