Using standardized source citation ratings in Family Tree Maker can help you make solid conclusions about facts. You’ve probably heard of original versus derivative sources, primary versus secondary information, and direct versus indirect evidence. That’s what FTM calls standardized source citation ratings. They also add a rating for clarity of the information–clear versus marginal. And both the Mac and 2012 versions support standardized ratings.
Unfortunately, the feature’s isn’t used by default. The source rating stars are there for you to set. The standard ratings are a bit hidden in the source rating window. The bonus is that by using the standard ratings, the number of stars is set automagically!
