Hundreds of archives, thousands of archives . . .

Terry Abraham of the University of Idaho has a great site for finding archives you need to look into at Repositories of Primary Sources. (I know, I know, sources are original or derivative; only information can be primary or secondary. Hide your eyes while clicking.)

The links are organized by continent and then (in this part of the world anyway) state or province). There is a form to submit if you find a broken link or want to suggest a new one (check his guidelines first, though). And bear in mind the comforting thought that items wind up in archives by the most circuitous paths, and the information you need may be housed thousands of miles from where the person in question ever lived.
