The Pulp Western: a popular history of the western fiction magazine in America is new on Archive.org and possibly a survey of interest to readers, re: the current interest in both ‘the weird western’ and in re-working western plots for new science-fiction and fantasy tales. It appears to have a strong focus on the writers and artists rather than the readers. Only a one-hour loan though. Texas Ranger Despatch magazine had a review, and it seems it can be picked up fairly cheap in user paper form if you shop around for it.
Another find was a magazine reprint of “Lurker in the Lobby #3” by Kennon James. The picture refers to Lovecraft’s one-time job as a cinema-booth ticket-clerk, which I seem to recall he took in order to save the cash for one of his antiquarian trips, circa 1929/30. I’ve never seen this one before.
Lastly, also now on Archive.org, The Bookman for key ‘Lovecraft years’. Again, with only a “one-hour borrow”.
