So I was wondering around Barnes and Noble (which happens to be a very bad habit of mine) see what is new and just checking out the books. Granted I was also straightening shelves and tables as well, I used to work there and old habits die hard.
So anyways, I digress.
Of all the steampunk themed books I think this was my best find:
This book had a lot of the history and progression of Steampunk. Let's just say I pointed it out to my husband as being on my Christmas list. I hate to say it but buy it from Amazon or from online at BN.com. In stores it was $35.00.
My best suggestion would be to go to the books store and just start to wonder around in the fiction, science fiction and teen sections. Just but looking at the covers you are now able to tell what books are going to have more of a steampunk theme to them. :)
To find it on bn.com or on amazon.com just search Steampunk History
