I am the author of two books: "Experimenting With Babies: 50 Amazing Science Projects You Can Perform on Your Kid" (http://www.experimentingwithbabies.com), which came out in October, and "Correlated: Surprising Connections Between Seemingly Unrelated Things" (http://www.correlated.org), which came out earlier this month.
One thing I didn't realize when I started pitching the first book was that there would be "passive income" in addition to the book advance and royalties.
For instance, I've had three foreign-rights deals for "Experimenting With Babies," and the only additional work I had to do was put my signature on some paperwork.
And I have Amazon referral links on both websites, pointing to each book on Amazon. Those links generate a monthly average of about $40 in commissions per month, although my monthly high has been as much as $630.
