We now know, since The Irish Times started printing sales figures alongside the books in the weekly bestsellers chart.
In original fiction, The Gathering is number five on the list with 334 sales last week, although the bestselling hardback novel, Lessons in Heartbreak, sold 2,496.
In hardback fiction Rhonda Byrne’s The Secret tops with 1,218 copies sold, but Rachel’s Food for Living sneaks in with just 168 sales.
In paperback fiction it took 782 copies of The Shakespeare Secret (don’t know it, but I’m guessing the title offers a clue to the genre) to get in at number five. In non-fiction, misery-lit Ma, He Sold Me For A Pack of Cigarettes, at number five, sold 273 books, only a few behind top-seller, the cult-took-my-children romp Escape by Carolyn Jessop (315).
In comparison, The Secret needed to sell 2,932 to reach number five in the UK harback non-fiction chart, while it takes over 21,000 sales to get onto to its paperback fiction list.
Keep in mind that sales are seasonal and that this is not the best time to flog books - the Spring season is still around the corner and during December (the boom time for books) sales can double week on week until Christmas Eve.
However, as a general point, it suggests that a book called, say, Please Don’t Beat Me, Da, Or I’ll Keep The Secret Of The Shakespeare Code has a good chance of getting in there on title alone.
