A friend read my post yesterday about adding all the books I read years ago to the Library section of this site. Their question was, “How do you know which books you read, and when, from so many years ago?”

Great question. The simple answer is that I remember most books I’ve read but I don’t remember exactly when I read them if it was before mid-2023. The detailed answer is that I buy all my books (mainly used) on Amazon.com, so my purchase history is there, going back over 10 years. I went through that history and noted all the books I’ve bought and the date of purchase. Some of them are still in the to-be-read pile. I’m adding those that I’ve read to the Library and using the Amazon purchase date as the month and year I read them. It’s not precise, but it’s roughly accurate, which is good enough for me. Done is better than perfect.
