Or you mean he'll probably already know about the paper? Yes, I guess that's probably the case...
I did not think about it too much to be honest, I just knew that article and thought that he would really like it if he had not read it. But I can imagine somebody writing a book on the history of Lisp has already read probably all articles around on the topic.
I just did not think about it for too long.
Yup, I know of that paper. The amount of (not or partly acknowledged) reading I've done for the book borders on the insane so I do welcome these suggestions, I've forgotten 80% of what I read and learning what others value helps me put together a "you really should revisit this" list :)
