Otlet's index card database

Almost a month ago, Johndan posted two entries on Paul Otlet's 1934 plans to create a mechanical index card database. I've wanted to read the article, muse on it, and post something insightful, but for now, but it's clearly not high on my to-do list at the moment. So, instead, I'm just posting here remind myself this all exists for when I return to "Memory and the Art of Database."
