Steampunk!

Steampunk is a genre-blend of historical fiction (often set in Victorian-era England, but may take place in other countries or past eras) and science fiction (an emphasis on steam- or spring-propelled gadgets).  If you're looking for more details about steampunk--what it is, some examples--Wikipedia (gasp!) has a pretty nice overview.

 If we allow ourselves to judge a book by its cover, Steampunk books are often easy to identify based on the book jacket.  They usually have a cover with a sci-fi / fantasy feel with lots of gears, clocks, and technology.
