What is the point of the above review? So 27 ISBNs failed, I wonder how many of them are not published by Pearson Education? Pearson Education is a publisher, who happens to provide their book catalogue online for all their titles and those of their associated publishers. They publish education titles, so searching for John Grisham or Terry Pratchett isn't going to get you very far!
