Robert Bloch (1917-1994) was a writer of the macabre, frequently with a sense of humor. It was he who said "I have the heart of a small boy. I keep it in a jar, on my desk", which is often misattributed to others, and especially to Alfred Hitchcock and, more recently, Stephen King. Bloch is best known as (1) the author of the novel _Psycho_; (2) as the writer of three episodes of the original STAR TREK; (3) as a member of the original "Lovecraft Circle"; and (4) as a very funny toastmaster/MC at a number of conventions and such.
This appears to be an unofficial book; at least, when I went back to look for it on Amazon, it wasn't there, and the link from Goodreads goes to a "we couldn't find that" page.
That's a pity, because it contains a number of quite good stories, including one minor classic.
Some of the particularly good stories:
"Hell on Earth" -- a "scientific occultism" story in which a scientist manages to summon and imprison Satan. There are consequences.
"Yours Truly, Jack the Ripper" -- this is the classic I mentioned. It's about a hunt for Jack in (then) modern-day Chicago.
"The Stange Island of Doctor Nork" -- what if Dr. Moreau had been in it for the money?
"The End of Science-Fiction" -- it turns out, sci-fi really _was_ bad for you. It's a darn good thing nobody writes it anymore.
"Tooth or Consequences" -- vampire + bloodbank + ...dentist?
"Founding Fathers" -- a time-travel caper story.
There are also several straightforward crime stories, some that are at least loosely Lovecraftian, and one short novel, _This Crowded Earth_.
Published in _Astounding SF_ in 1958, _This Crowded Earth_ may not be the first serious speculative novel about overpopulation, but it's certainly a very early one, and the earliest I know of in which someone actually comes up with something -- other than war -- to do about it.
Harry Collins is an ordinary schlub who hates the way things are soo crowded in Chicagee (a megalopolis, and predecessor to things like "Boswash", "San Frangeles", and, of course, "the Sprawl"; there are several named in the story), and in America in general. Eventually he is forcibly kept from leaping from a high window and taken to a mysterious health facility. Here he is given a course of treatment that, ultimately, involves impregnating a couple of nurses, each of whom he never sees again. A mysterious stranger informs him that this facility is the testing ground for ... something ... which is surely an answer to global overpopulation.
Lots of plot (and civil war and such) later, it turns out that the "something" worked too well, and is on the brink of bringing the human race to its final end. This is in turn resolved, bringing the book to a satisfactory (in Campbellian terms, at least) ending.
It is a work of classic "Golden Age" science fiction, with problems, solutions, and consequences of the solutions that turn out to need their own solutions.
To sum up: since I can't recommend this collection because it has rather mysteriously ceased to exist, I can comfortably recommend its contents, wherever you may find them.
