read on a news site:
"It seems that the only content of most of these books printed consists of open access articles from Wikipedia, without any indication of the involvement of these three individuals in their drafting. The books often have very long titles full of words- . The key items are often poorly printed with the characteristics of the missing characters in languages other than English (note: with the e-focus does not pass apparently) and many arrows images where proposed a Wikipedia link .. . "
I did not buy much on this lie.
