According to the Association of American Publishers (AAP) StatShot monthly revenue report for April, sales revenue in the adult fiction/non-fiction hardcover category beat eBooks for the month. We’ve embedded the April chart above.

Here’s more from the report: “For April, Hardcover returned to the #1 spot for sales revenue for Adult Fiction/Non-Fiction ahead of eBooks, reflecting seasonal buying patterns (if you recall, these rankings were switched in March).  In [year-to-date revenues], eBooks remained as the #1 format in Adult F/NF as it did last month but with a much narrower margin.  Both Hardcover and eBook revenues increased vs April 2011 and vs YTD 2011.”

In addition, the publishing industry saw a five percent increase in April sales revenue compared to the same period last year. The association collected data from 1,187 publishers to compile the report.
