The Pulp Publishing Spreadsheet

Jess Nevins never fails to amaze me.

…if the pulps are supposed to have died around 1950, why were there so many pulps published after that? Certainly, it seemed to me that there were a lot of pulps published after 1950, and that the "death" of the pulps was overstated. But there was really only one way to resolve this: a spreadsheet (Yes, I’m a stat wonk, I guess)…

And, at the link, you will find the link to said spreadsheet, as well as all the relevant history, explanations and details.
