BSFA Award: second round stats

The BSFA has announced the opening of Round 2 of this year's BSFA Awards. This time round, nominations were accepted in all categories to the end of December; we now have January to winnow down the candidates to a final four in each case. As usual, the list of Best Novel options gives me grist for my statistical mill: here they are, listed in descending order of aggregate popularity on Goodreads and LibraryThing (the number in each case is the number of users who own each book).

It becomes painfully clear that Goodreads has about 80 times as many users as LibraryThing!

I'm baffled by the one book which has hundreds of Goodreads owners, but none at all on LibraryThing as far as I can see. Sure, it's self-published (and you'll spot some similar patterns on the list), but that skew is extraordinary.
