"A company variously calling itself Alphascript Publishing and Betascript
Publishing is taking articles from Wikipedia and publishing them as books.
It would appear that the act of doing that is legal, but from the outside,
many of the books give the appearance of having been put together by some
automated system, because the titles (and presumably contents) seem to be
comprised of a Wikipedia page forming the starting point for the book and
then a load of other Wikipedia pages which are linked-to from that page"
