Finally, is there a place at Wikipedia (I know of several elsewhere) for registering such spiders with descriptions and contact information, in case someone observes the spider working and wonders, or in case there is some sort of problem?
You should probably register a username specifically for the bot (for example: World History Bot) and then leave your information at [[User:World History Bot]].
