Looking at my workload over at Civil War Book News, I'm seeing a pattern in Civil War summer publishing: I found 21 titles released in May, 43 in June, 23 in July, and when August finishes that month will have seen 33 new ACW books.
I have an idea about the June surge: publishers are mindful of beach reading. August, I'm not clear about, unless the potential of assigned school reading is making that number higher.
p.s. I reformatted this website into a blog in spring and will need to backfill Jan - Apr.
