Keep a clear research log
Because genealogy research typically takes a significant amount of time, it is very easy to misplace information. Encourage you to keep a clear research log detailing everything you do, learn, and still need to learn to stay organized and make the best use of your time.
One simple method is to use the genealogy software mentioned above. However, you may want to keep hard copies of important information as well. You could even set up a pin-up board or blackboard to brainstorm and connect ideas if you like to visualize information.
It's also a good idea to keep a separate contact log. You should keep detailed records of everyone you've spoken with during your search. Take down phone numbers and email addresses, and make a list of the people you still need to contact.
