The year in the HN title looks wrong, in the PDF it says 2019, please fix it, otherwise people ignore the book thinking it's too outdated.

Oh wait. I stand corrected - I missed that it said "Copyright 2009", "First printing 2019", not sure why it took so long to get it printed.

It's explained on the web page

"After ten years in print, our publisher decided against further printings and has reverted the rights to us. We have published Elements of Programming in two forms: a free PDF and a no-markup paperback."
