Эй, are there actual super natural Книги I can read. Also how about items such as t-shirts posters & such?

Well, they do have alot of merchandice... but yes, there are actually Книги Ты can read, the novels that is. However they can sometimes be a challenge to find...
They have t-shirts, posters, mugs, dogtags and even calenders! Here's a great site to use:

There are about 5 или 6 Сверхъестественное novels out. I've read two: Witch's Canyon and Nevermore; they're ok. What's really cool are the comic Книги which are a prequel to the show. If that's your sort of thing I'd definitely check those out.

^There is also a 'Supernatural Book of Monsters, Spirits, Demons, and Ghouls' Here's a pretty cool description:
>>A one-of-a-kind compilation of all of Sam and Dean's demon-busting knowledge, The Сверхъестественное Book of Monsters, Spirits, Demons, and Ghouls contains illustrations and detailed descriptions that catalogue the еще than two dozen otherworldly enemies that most people believe exist only in folklore, superstition, and nightmares:vampires, ghosts, revenants, reapers, and even bloody clowns. You'll find within these pages Sam and Dean's notes, observations..<<

^Another cool book is John Winchester's Journal.
>>Part prequel, part resource guide, John Winchester's Journal finally gives Фаны the ultimate companion book for Supernatural. It's all here: the exorcism Sam and Dean used in "Phantom Traveler," John's notes on everything from shape-shifters to Samuel Colt, Dean's first hunt, Sam's peewee Футбол team . . . and John's single-minded pursuit of a growing and deadly evil.<<

Those two I think are the best for hardcore Фаны and Фаны who are curious to see just how much knowledge the Winchesters have.

yes they do. Ты can go on link and look up Сверхъестественное and they have a lot of things that's were i got mine books.
