Legends What are some good Star Wars trade paperbacks?

You could go for the Thawn Trilogy and the Shadows of the Empire dulogy, as well as the Dark Empire trilogy. Those should do the trick.

If you want even more, buy the TPBs for the Republic ongoing series. Well, it's not ongoing anymore.

 

Crimson Empire, Volume 1. I didn't care for Volumes 2 or 3. But I think all three are collected presently in a hardcover edition.

Series: Knights of the Old Republic, Dark Times, Legacy, Agent of the Empire

Star Wars Republic (the series is now in three omnibuses: The Republic Goes to War, The Enemy on all sides, The Republic Falls)

Tales of the Jedi omnibuses (if you are interested in ancient Jedi history)

The Legacy series are superb and take place 125 years after ROTJ. Seriously epic
