"All About Monsters" (written by Carey Miller, published by the EMC Corp., 1977) is one of three books in a series called "The World of the Unknown" which got regular circulation at my school library (and it looks like the ex-library copy I've scanned here saw plenty of action as well).
It really does try to live up to its title by covering all categories of "monsters", from Greek and Roman mythology (Cyclops, Sirens), to Old English literature (dragons and Beowulf's Grendel), cryptozoological legends (Bigfoot and the Loch Ness Monster), and real-world prehistoric dinosaurs. There's even a section on famous monsters of film and creature make-up effects, and finally a monster dictionary.

This is a pretty thin book (only 32 pages!) to endeavor to cover so much information, so no subject is covered in depth. Instead we get well illustrated spreads that briefly introduce each topic, but leave you to pursue deeper studies elsewhere.
The "Man-Made Monsters" (aka movie monsters) section features an eclectic assortment: King Kong, Mecha-Kong, Frankenstein, Jaws, HAL 9000(!), Godzilla, the squid from "20,000 Leagues Under the Sea", and the Mummy.
This modest (only 2 pages) monster dictionary was my favorite section.
These cover images from the other two books in the series are found on the rear cover of "All About Monsters".
