Comment: While the current article is  coupled with an indiscrimiante list, and probably qualifies for , I did find a source for the general analysis, ''The Greenwood Encyclopedia of Science Fiction and Fantasy'' (Gary Westfahl). It has two and half pages about Earth (and a dedicated entry to it), at https://books.google.co.kr/books?id=SQMQQyIaACYC&lpg=PP1&dq=science%20fiction%20encyclopedia&pg=PA226#v=snippet&q=earth&f=false (p.226-228). Sadly there is no entry in ''The Encyclopedia of Science Fiction'', ''The Mammoth Encyclopedia of Science Fiction'' (George Mann), ''Encyclopedia Of Science Fiction'' (Don D'Ammassa), 'The New Encyclopedia of Science Fiction'' (Jame E. Gunn), and ''The Encyclopedia of Fantasy (Clute and Grant). Anyway, we have one source but GNG requires multiple; that said it is an encyclopedia, so it's probably is enough? Sadly I can't see page 228, only 226-227, so I am hampered in my ability to rescue this using even this one source :( Ping
