Being of a statistical bent, I have a couple of questions that I hope someone on the forum might be able to answer:
1. Does anyone have word counts for Twain’s full-length books? I think I’ve seen him mention such things in his letters or maybe his notebooks at times, but I never made any notes.
2. I’m also interested in sales figures for his major books – say, the number of copies sold in the first year after publication. Years ago I found numbers for Innocents Abroad (69,156), Roughing It (65,376), The Gilded Age (50,325), Sketches New & Old (27,118) and Tom Sawyer (23,638), but I don’t remember where they came from, and I’ve never seen comparable figures for the later books. Are those available somewhere?
