Do you need to bone up on one of Michigan's astonishingly numerous counties? The Clarke Historical Library at Central Michigan University has you in mind with its collections of books and theses pertaining to each county. If you don't know the difference between Wexford and Missaukee this is your chance! While you're there, check out some of their other resources like the manuscript finding aids and the index to the Michigan Historical Review, or else I'll blog about them in the future . . .
