I started digging into a complete collection of tales and poems by E. A. Poe. Haven't gone far yet, but I already knew the poem The Raven. Also, it seemed like a reasonable next step after reading that Poe had some influence on H. P. Lovecraft.
The Complete Adventures of Charlie and Mr. Willy Wonka by Roald Dahl. Nearly finished it. Next time I go to the library I wish to find some good book, some fantasy book, a murder-mystery, detective book or a horror-but-not-too-scary book.
I'd so want to find a cool vampire story. What makes me the most sad is that I couldn't find one of my favourite comic artists' works from there although I was sure that I'd seen them there before... Oh, Iznogoud...
What am I reading right now? Why, Cases in Comparative Politics. It's fantastic.
Also, I don't know the extent of what's been recommended at you, but The Complete Hitchhiker's Guide to the Galaxy is always a good way to spend a week.
