Research Logs may seem superfluous, but they are an important tool when researching your family tree. It is important to record every place that you look for information, whether you find anything helpful or not. This will help you to not repeat searches in the future. When recording your search, be certain to record what, specifically, you were looking for. You may want to consult the same resource for multiple items. Research Logs are also a great way to plan for a visit to a library or archives. Listing everything you wish to examine on your visit, including call numbers or reference information. This can increase your productivity at the repository.
