"...The November AAP data is provided by 77 U.S. publishers, with 26 of those additionally providing e-book figures (though not all of those are trade publishers). The AAP cautions that its monthly statistics should not be compared directly to BookStats, the AAP's recently launched joint venture with the Book Industry Study Group, which will include data from nearly 2,000 publishers and will be published annually. Rather, the monthly numbers provide a general sense of broader trends in book publishing."
