FamilySearch.org, the free online genealogy service, has a staggering library of free online genealogy courses. The courses are in the form of videos.
There doesn’t seem to be a topic that these videos don’t cover. From understanding Swedish and German birth records, to interpreting the information on Scottish, Irish and English census records to how to organize your research…there are very, very few topics that haven’t been covered.
It’s a goldmine of information for seasoned and newbie genealogy researchers.
