The 30-year relationship between Lucasfilm and Random House is now heading into the eBook frontier in full force.

The entire backlist library of Star Wars fiction titles under the Del Rey and Bantam Spectra imprints will be available in eBook format starting June 28. Under the partnership, Random House will convert more than 100 backlist titles into digital editions, along with any future Star Wars novels presently in production. The titles will join the 30 Del Rey Star Wars novels currently available as eBooks.

All Star Wars eBooks will feature extra content including an introduction to the six major Star Wars eras: The Old Republic, Rise of the Empire, Rebellion, The New Republic, New Jedi Order and Legacy.

Del Rey Books published the novelization of the first Star Wars film more than 30 years ago.
