Of all the Bantam novels I bought, the only ones I bothered to keep were the five Thrawn books (the trilogy and the Hand of Thrawn two-parter) and the Han Solo trilogy by A.C. Crispin. Everything else was more or less forgettable, or at least not worth the effort to preserve for future reading.
The only Del Rey books I bothered with were Outbound Flight and Survivor's Quest (because they addressed the Outbound Flight thread from the Thrawn novels). The latter book didn't suffer from as much "prequelitis" as the former, which was set during the prequel era (as it was established that Outbound Flight had been launched during that period of time). I'm really only keeping them because of their ties to the Thrawn novels.
