As printed book sales pass the £1bn mark we ask…what’s the best book you’ve bought this year?

It’s taken printed book sales two weeks longer to reach the £1bn mark this year than in 2010.

£29.5m was spent at UK booksellers in the week ending 24th September, bringing the total for these 83 weeks of 2011 to £1.008bn, which is down 5.3%, or £53m on 2010, when book sales passed the £1bn mark on 11th September.

The decline in printed book sales is largely down to the transfer of sales from print to digital, with recent reports from many UK publishers showing digital book sales now account for a whopping 9-10% of their overall book sales, compared to 4-5% last year.

Figures show that novels have been hit the most by the move to digital (click here for You’re Booked’s feature on e-books vs real books to have your say on this hot topic). Fiction titles dominate the Amazon Kindle, Applie iBooks and Waterstones.com e-book chart and spending on novels is down around 10% year-on-year. Comparatively, spending on non-fiction books is actually slightly ahead of last year, while children’s book sales are down slightly, due perhaps to a decline in the popularity of dark romance novels.
