Sheldon started keeping an online journal on November 8, 1998. He posted synopses of his thoughts and activities, comments on books, films, TV shows, and music both live and recorded. He wrote his final note on the day he died, February 4, 2008, 9 years ago. The first page, from 1998, links back to a “1975 Retrospective,” which links in turn to a “1971 Retrospective.’

He used the photo here in the 1971 retrospective — a selfie — from 1971. Sheldon was way ahead of the crowd with selfies!
