If you happen to have an Amazon Kindle (you lucky dog!), then you might be pleased to know that there are a ton of free Amazon Kindle books available. It might be worth scooping up a bunch of them for later even if you're not looking for anything new to read now.
I know some of my friends complain that reading books and newspapers on an electronic device is sacrilege and I sort of agree. However, as I recently packed to move, I realized I owned enough books to fill the Ancient Library of Alexandria. Captain Beatty would fry me alive if he discovered my hoard. I'd probably thank him too. Just the thought of moving them again is giving me a hernia.
