Minor progress

A minor mishap, with maybe an update or two lost. I didn't keep my list of specific areas updated, but I've made substantial progress in checking the links from history to particular cities, and a large number of links from modern history. I also completed the initial review of links from Sociology. Sometimes it's tempting to say. "It's all important!" and check everything, but that's not the idea. I skipped the opportunity to use it for a somewhat connected survey of history, and have selected a bunch of lower-level topics that I've been wanting to get to for some time. i seemed to make more progress in religion than anything else, but most of that was link-checking.
