This is the extent of my interest in Star Wars novels because they all take place in the 1977 universe;
Splinter Of The Mind's Eye is my Spring\Summer read, the Han Solo Adventures by Brian Daley are my Autumn\Winter reads. While the published NPR Star Wars (also by Brian Daley) isn't EU, a few chapters venture away from the film substantially in story & characters. In that regard, it's definitely extended.
I've perused the EU section at Border's, but I've never come across anything that interested me. I'll probably get the Lando books by Niel Smith because they're also set in the 1977 universe.
