Actually I guess The Han Solo Adventures wasn't the first, at least not the collection because from what I can see that wasn't released until a year after Heir To The Empire and I bought that right when it came out. I had read the Han Solo Adventures books prior to Heir To The Empire but it must have been the individual books though I don't recall actually owning them so I think they may have come from the library. Which would make Heir To The Empire the first piece of EU that I owned. Speaking of which I have recently thought several times how much I wish I still had those old hardcovers of the Thrawn Trilogy I bought back in the day. Or rather my parents bought for me, I didn't have a job at 11 years old. They're my favorite Star Wars books and I bought them right when they came out, but back in college they were among several stacks of books I took down to the secondhand bookstore to sell for beer money. I have replaced them with some pristine secondhand copies I found but I wish I had the actual ones I read as a kid.
