Bowker released a report today on U.S. Book production.  Among their projections:  U.S. book production in 2009 remained flat but 2009 was an extraordinary year of growth for “non-traditional” books.  According to the press release,  these [non-traditional] books, marketed almost exclusively on the web, are largely on-demand titles produced by reprint houses specializing in public domain works and by presses catering to self-publishers and ”micro-niche” publications.  Bowker projects that 764,448 titles were produced that fall outside Bowker’s traditional publishing and classification definitions.  This number is a 181% increase over 2008 — which doubled 2007’s output – driving total book production over 1,000,000 units for the first time. ”
