In 1964, the Hugo for Best Novel nominees were:
Way Station won with a total of 63 votes. Witch World and Glory Road tied for second, with 54 votes apiece. 7 voters felt like none of the above books were worthy of the Hugo.
In 2013, the Hugo for Best Novel nominees were:
Now, for fun, here are the books in Amazon rank order (for purposes of unit comparisons, kindle edition ranks are used wherever possible), from lowest (least sales) rank to highest:
*Way Station, by Clifford Simak, appears to be unshepherded by its rights holder: it is available under numerous publishers, in many editions, but not kindle. The sales rank reflects the best rank of only one edition of the book, and there are no authorized new in-print editions listed.
**Witch World, the book that launched the massive and still popular Witch World project, has not been updated for publication in quite some time. It too suffers from the same disunion as Way Station: numerous copies are available in print, but not yet in authorized ebook. For example, Wizard’s World, one of the newer Witch World books for kindle, ranks at #33,196, which would put it in 6th place on this list if it counted.
Note: Amazon ranks are, of course, transient things, a basic fractal pattern, so this is just a snapshot in time, and can’t be used to make anything but the most generic sales observations, but they are interesting for other reasons. Generally speaking, something in the top 10,000 is likely doing better than the top 100,000 currently, but the difference between 20,000 and 60,000 is (again as a momentary snapshot) negligible for unit sales comparisons. I looked up these ranks prior to the 2014 Hugo nominees announcement.
