I don't think it has been mentioned here, but there is a new book
"Confederate Civil War Blockade Runners 1861-65" in the New Vanguard series
published by Osprey Publishing. This is a series on various types of naval
vessels, aircraft, etc. The book is paperback, 48 pages with 8 pages of
colour drawings. The author is Angus Konstam and the illustrations are by
Tony Bryan. Most of the blockade runners were paddle steamers. I haven't
read the book fully yet, but bit gives a good overview of the subject and is
only 8.99 GBP.
In the same series and recently published are "Mississippi Gunboats of the
American Civil War 1861-65" and "Union River Ironclads" by the same author.
The books can be ordered direct from the publisher
