Notes

This list is not complete and emphasizes regular refereed journal articles. It also does not include edited books, book reviews, or Web materials. Some reprints are available, as linked, and others are available on the most excellent ADS. Yes it's true, I do seem to have taken long rests in 1968, again in 1989, and possibly in 2018.
