Publishers Weekly has the numbers on The Bestselling Books of 2014 in the US -- sort of.
Annoyingly (lazily ? and bafflingly), they count separate editions separately, so, for example, three editions of Gone Girl make the top six of the 'Nielsen BookScan Adult Fiction Top 20' (trade paper: 962,797 units; movie tie-in: 458,245 units; mass market: 415,253 units -- all from the same publisher) and true totals are a bit hard to determine.
As usual: the only one of these titles under review at the complete review is Donna Tartt's The Goldfinch.
