Here is another great book I used to have when I was much younger, The beaver book of horror by Daniel Farson [grandson to Bram Stoker]. What especially attracted me to this book was this wonderful painted cover by Alan Lee, which extends to the back of the book too. I kind of love the innocence of the characters, even though the monsters look quite grusome, they also look innocent enough to just look at the book the children are reading. For some reason I can't find any pictures of this actual painting, even on websites about Alan Lee and his work.
The book itself covered a wide spectrum of subjects such as true stories about ghosts, vampires, werewolves etc, as well as people such as Vlad the Impaler, Countess Bathory, Rasputin etc. There is a look at the classic horror stories such as Dracula, Dr.Jekyll and Mr.Hyde, Frankenstein etc. An almost human section that looks at The Elephant Man, wolf children, The Lambton worm, etc. other sections include Horror on stage and screen and a guide to places of horror such as Translyvania, Haiti, Whitby, Highgate cemetery etc. This is a highly recommended read and has 16 pages of photos. 206 pages of grusome reading.
