Bloomsbury Publishing, the British publishing company that published the Harry Potter books, reported that its global eBook sales rose 70 percent year-over-year, during the period of March 1 through May 31st, 2012.

The company issued its Interim Management Statement last week, and revealed that print sales during the same period fell by 2 percent. ThisisMoney.co.uk has more: “Last year print sales were £78.9million and those for ebooks were £5.7million, meaning that if the latest trends continue throughout the year, they would result in an overall rise in turnover.

Bestselling titles that helped the publishing house during the period include: Hugh Fearnley-Whittingstall‘s River Cottage Veg Everyday!, Wisden CricketersAlmanack 2012, Double Cross by Ben MacIntyre, Heston at Home by Heston Blumenthal and Salvage the Bones by Jesmyn Ward.
