The Arthur C. Clarke Award shortlist has been announced, and the popularity of the six books on Goodreads and LibraryThing is as follows:
| Goodreads | LibraryThing | |||
| owners | av rating | owners | av rating | |
| The Underground Railroad, Colson Whitehead | 240219 | 4.05 | 1602 | 4.09 |
| A Closed and Common Orbit, Becky Chambers | 15509 | 4.4 | 190 | 4.37 |
| Ninefox Gambit, Yoon Ha Lee | 13440 | 3.96 | 219 | 4.02 |
| Central Station, Lavie Tidhar | 4835 | 3.53 | 124 | 3.77 |
| After Atlas, Emma Newman | 1948 | 4.21 | 49 | 4.38 |
| Occupy Me, Tricia Sullivan | 794 | 3.46 | 33 | 3.55 |
The standout for me is After Atlas, which despite being owned by the second fewest number of users of both systems has the highest rating on LibraryThing and the second highest on Goodreads.
Though it's also arguable that it's more difficult to retain a high ranking as the number of people reading the book increases and more people who don't like it record their opinions, in which case A Closed and Common Orbit also looks good. (And The Underground Railroad doesn't look bad either.)
