THE FIRE CAME BY by John Baxter & Thomas Atkins

Dense little volume delves into THE RIDDLE OF THE GREAT SIBERIAN EXPLOSION! Loads of historical background, especially focused on Soviet hero scientist Leonid Kulik and his multiple expeditions to the devastated fall site deep in the blasted hinterlands of Siberia. The co-authors conjure up an out-of-control spacecraft's nuclear overload for some light science fiction on top of everything else. Recommended.

THE HIDDEN SECRETS OF THE HOLLOW EARTH by Warren Smith

Self plagiarism in Pellucidar! 

Warren Smith rips off his own co-pseudonym "Eric Norman" and his previous volume This Hollow Earth, copying chapter by chapter into this so-called "special report." Little effort is made to disguise the recycling beyond some shuffling in chapter order and occasional change in word choice. Only two sections of the book seem original to the new edition: a brief digression on the Eskimo, and an interview with Ivan T. Sanderson.

Table of contents for Smith's new work:

1.  Mystery of the Hollow Earth (5)

2.  Legends of the Inner Lands (21)

3.  Deros, Teros, and the Shaver Mystery (40)

4.  Enigma of the Polar Openings (69)

5.  Tamil and the Genesis of the Cave Masters (102)

6.  Shamballah: A Paradise Inside Earth (132)

7.  Enigma of the Eskimo (148)

8.  They Believed in the Hollow Earth (163)

11. Vril Power and the New Race (219)

12. Adolph Hitler: Messiah of Hollow Earth Lore (229)

13. A Scientific View of the Hollow Earth (243)

And once again from This Hollow Earth, for comparison:

1.  The Weird World Inside the Hollow Earth (5)

THE WORLD OF THE PARANORMAL by Walter McGraw

Pyramid Books, 1969

STRANGE GUESTS by Brad Steiger

Another ghostly hit parade from Ace Books, this time collected by dependable working writer and "occult authority" Brad Steiger. Paranormal pop-sci titan Ivan T. Sanderson uses his introduction to frame our terror tales as a frontier of expanding Space Age science, but we all know we're really here for THE BUG EYED MONSTER'S INVISIBLE FANGS.
