The American Bar Association has book called the Guide to Wills and Estates available for downloading from their website. The book guides you through the different estate planning tools, and talks about how planning now makes things easier for your family later.
While advice from a book does not replace a relationship with an attorney, it can certainly help you figure out what you want your plan to look like, and help you understand some of the things you'll be talking about with your attorney. And, the book is written with general advice that is not specific to any one state, so keep in that some terms or processes described in the book might be slightly different in your state.
If one of your New Year's Resolutions is to get your estate plan in order, this book can be helpful in getting you started, but you still need to be the one to actually call your attorney and make the appointment.
