Back in 2003, Jean-Paul Allouche and I published a book, Automatic Sequences, with Cambridge University Press. There's some info about the book, including errata and some reviews, here.
Just this week, our book reached a milestone we could not have anticipated 12 years ago: 1000 citations on google scholar:
Of course, this number is a bit misleading, since it double-counts papers on the arxiv that later appear in conferences and journals. Nevertheless, I'm really pleased that our book (despite its defects) has been so useful and influential. And thanks to my great co-author, Jean-Paul Allouche!
