I discovered two new facts about Laura. The first is that my 148 diaries represent only about one eighth of the total number of volumes Laura wrote. It turns out that I don’t have a single complete year after 1962, and that almost all the 70s, the second half of both the 60s and 80s, and most of the 90s are missing. Estimating from the gaps in my collection, the correct total number of books is closer to 1,000, or 40m words. Laura was the most prolific diarist in known history.
