To my clients, I offer a fee free lending liabrary. I have a variety of pregnancy books, from babyname books to the classic "What to Expect when Your Expecting". Even books just for dads! Due to problems in the past with free lending liabraries, I do ask for collateral. A check for the price of the book to be cashed to buy a new copy if you decide to skip town with my very expensive chilbirth books and videos is now a requirement.
