First off, don’t get TOO excited. The figures are very impressive, but they carry some health warnings the three biggest:

• Ebook sales are undifferentiated whereas print sales are segmented
• Thess are self reported and not the whole market
• These may still be seeing post-Christmas loading by new ereading consumers

That said, the market is clearly growing VERY quickly still. Read the whole release from the AAP here.

Sales of e-books in February tripled over the previous year to $90.3m, the Association of American Publishers reported, exceeding adult paperback sales of $81.2m.

A 169 per cent surge in e-book revenues since the start of the year contrasted with a 24.8 per cent decline in print book sales to $442m over the two-month period. February figures showed steeper declines in some print categories, with adult hardcover sales falling 43 per cent to $46.2m and mass-market paperbacks down 41.5 per cent at $29.3m.
