Del Rey has put a wealth of Expanded Universe ebook material on sale today. Perhaps a better way to phrase that would be a wonderfully staggering amount of ebook material on sale.

First off, both the Essential Guide to Warfare and the newly released Essential Reader’s Companion (Have you read our review yet? You should) are now available in electronic format. These editions are complete with all the illustrations that appear in their paperback counterparts, so if you own a tablet this could be a very interesting option for you.

As we mentioned yesterday, an essential novels bundle containing Heir to the Empire, X-Wing: Rogue Squadron, Vector Prime, and Legacy of the Force: Betrayal goes on sale today for only $7.99 total. A larger 10-novel bundle can also be purchased for $62.99.
