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.
Here is a list of some YA Steampunk books and series that have been published recently, although this is by no means a complete list:
