Probably an upcoming topic for http://conchologia.com, but in addition
to these examples (in which basically someone is selling printed
Wikipedia content, not even reliably selected as relevant to the given
title), one can also find advertisements for what sounds like various
existing publications, mostly older ones, but in fact are merely bound
copies printed off of sources such as Google Books, Biodiversity
Heritage Library, etc.  In addition to the fact that you could print
them yourself instead of buying them, there is the problem that
scanning and/or digitization errors mean than those copies often have
serious problems, particularly in the illustrations.  (Hint to Google:
if there is a fold-out illustration, a scan of the folded up page is
not going to make the user very happy.)
