Two fifty year old classics of SF, Isaac Asimov's I, Robot and Ray Bradbury's Fahrenheit 451, show up prominently on lists again this week, Asimov's among the top 50 on 3 lists, Bradbury's in the top 75 on 2 lists.
Stephen King's Song of Susannah is still doing well on 6 lists in its 16th week on this chart (including pre-publication rankings). Karen Joy Fowler's The Jane Austen Book Club is still on 5 lists this week, its 12th week on the chart.
BookSense hasn't updated its chart in the last week. The link to BookScan, a site presenting Nielsen Bookscan data from the UK, now redirects to another site; if this change is permanent (such data from the US is available by paid subscription only), that column will be replaced here by the Top 100 rankings from Amazon UK.
(Bookmark this link, Locus Online Bestsellers, for automatic redirection to the latest week's chart.)
