I have started pulling the Spring list of Civil War titles together to update Civil War Book News and noticed that there are already over 450 ACW listings for this year (2005) on Barnes & Noble. More forthcoming books will be posted to the B&N site as we approach December; add to this the stuff that does not make it into their purview, and we are looking at a total well north of 500 by year's end.
When I started my list in 1998, a year could yield, with some hunting and checking around, news of about 200 titles.
