It is never too late to start logging your sources. Knowing
where you gathered particular details on an ancestor is very
important in your research. When evaluating incongruous
information, reviewing which source the details are from can
help you decide what is more accurate. Another reason to keep
track of your sources is so others can verify or follow-up on
your research. Some ways you can keep track of where you found
information on your ancestors are: 1. Maintain a log of sources
in a notebook or on your genealogy software. 2. Copy the title
page of sources you have viewed. 3. Note materials you have
searched, but in which you did not find information. It prevents
you from repeatedly returning to the same source.
