Sources and Factchecking
For all of the advancement that the internet has allowed there is still nothing like a good relationship with your local library for a writer. There are some sources of information that cost money online; reference books about very specific times and places for instance that are free at the library. There are even some resources that are not available at all online believe it or not. There are times when the power or internet goes out (yes it does happen) that it is good to have a hardcopy around. So go find your local branch and learn to cozy up with twenty odd pounds of cellulose, cardboard, and cloth.
