Five links for a final Friday (August)

Plenty of good reads this month:

1. I recently stumbled on Litographs, gorgeous prints made from the text of famous books available on Project Gutenberg. With every sale, they send a book to a community in need.
2. Many of the 21 tips to make the most of your freelancer are aimed toward presses, but they apply to authors, too (see #1, 3, 5, 6, and especially 20).
3. The more you know: MLA develops a standard for citing tweets.
4. Ever wonder where your lost mail went? I always imagined a giant storehouse of letters, and it turns out I was right!
5. Travel from another time: Loving the colors and scenes in these motel postcards and vintage photos.
