We’ve got a new map of Rav Yosef Shaul Nathansohn’s Sho’el U-Meshiv. He wrote more responsa than there are pages of Talmud. If one learned Sho’el U-Meshiv Yomi it would take longer than Daf Yomi. That’s really something.
Anyhow, we mapped it. You can toggle both city maps and heat maps for Sho’el U-Meshiv and Maharsham. They were both Galician, one generation apart, so it really offers an interesting basis for comparison. I haven’t even started digging in.
