Wikipedia:Articles for deletion/List of Martian canals
The topic of Martian canals is notable (they have an WP article).  I have added links to articles in Nature and Scientific American about them.  Obviously the theory turned out to be bogus but that does not diminish from the considerable time and investigation by leading academics (plus wider public) in this issue (there are loads of references to this topic on any google search).  My issue however is where this exact list came from? I have added external links to PDF copies of Lovell's book and the relevant Chapter IV on the Canals.  However, I am not sure how this list compares (it is not a direct extraction).  I guess we still have a potential  issue (but not a notability issue), but given that the lists/diagrams exist, it it solvable task, and clearly someone went to great trouble to complete this list many years ago implying that it is probably right.  However, all of this should no prevent the article from being kept
