Just a reminder that Episode 15 of my Vacation in the Golden Age is coming this Sunday, May 15. It covers the September 1940 issue which contains part 1 of A. E. van Vogt’s “Slan”, as well as stories by Heinlein, Hubbard (von Rachen), Asimov, and a science article by R. S. Richardson. It’s a very good issue; if you’ve been following along, you won’t want to miss this one.
