Began work on preparing for the presentation in May, and started by gathering some screenshots and making a rough plan. In the process, we began to examine the page-images for the community directories, and I think (based on my limited Japanese) that I've discovered a discrepancy; a directory we believed (based on UBC metadata) to be 1939 actually looks to me as though it's dated 1941 (Showa 16). Waiting for some expert help to confirm or dispel this suspicion.
