Celebration of the 200th birthdays of Charles Darwin and Abraham Lincoln yesterday reminded me that there are fascinating blogs devoted to both subjects. There's general interest in Darwin on Cliopatria's History Blogroll at both Digital History, Science, and Technology and at Modern History. But, for particular interest, check out: The Beagle Project, Blogging the Origin, Darwiniana, and The Dispersal of Darwin. Similarly, there is general interest in Lincoln at both Military History, where over two dozen blogs focus on the American Civil War, and United States History. There, A. Lincoln Blog, Abraham Lincoln Blog, Lincoln Studies, and What Would Lincoln Do? feature Father Abraham 365 days a year.
