So freaking glad I read my books on a Kindle now. Packing up and trying to decide what to do with the books I do have really sucks.
Yeah, last time I moved I really second guessed bringing all these old (and very heavy) textbooks I had. I barely used them when I took the courses, it's pretty unlikely I'll use them again. Especially when most of the content is likely available in online sources.
We ended up packing most of our books into rolling suitcases, better than boxes since you don't have to lift them.
