From the top of corpsepile of history comes a voice: I’m not dead yet….
Of course, if you don’t like clutter, e-books are great; but if you love books, lots of them stacked up is comforting. And the used book market is still a relatively strong one, so just sell them if you don’t want to keep them around. You can then buy more books, something you can’t do with electronic copies of books. I buy used books for $5-8 each, then sell roughly two-thirds of them back to the bookseller for $3-4 credit. So new used books only end up costing me a few bucks, or I can put my credit towards a new title, cutting the cost below that of an e-book copy. Unless you’re buying new books all the time, I’ve found digital copies to be a significantly more expensive way to go.
