The joy of electronic books

Having digital copies of my books sounds great, but as a college student I'd like to sell some of my books back at the end of the semester. I'm not sure how interested the book store would be in gorilla-glued spines.

I was recently reading a very detailed instructable [1] that describes a system to scan books without cutting the spines for ~$300. I'm planning on trying it out later this summer.

Is there a legal way to sell used digital books or used digital music?

Like some app where you identify the mp3's that you'd like to sell. The price is half of itunes. When a user buys it, the app "permanently destroys" (yeah, yeah, i know) your copy of the mp3 and transmits the mp3 to the buyer.

Re-selling goods is a long-standing fixture of the economy. Doesn't it apply to digital goods too?

The only problem with digital copies like this is that I can't underline. Maybe it's just the habit of underlining, but I can't read as well (academic reading) when I can't underline key points, specific words, and particularly interesting passages.

Ha! The Longview/Marshall phonebook!

LeTourneau, by chance?

He hates DRM but uses an iPhone?
