You will need to be inside the library using either a public access computer or be connected to library Wi-Fi in order to use Ancestry Library Edition.
You will be able to search census, military, immigration, birth, marriage, and death records for your ancestors. While all of the research must be done through the library, you can have documents emailed to yourself. After the email comes through, these documents will be available to you wherever you are! Your research will not be saved automatically, so be sure to keep track of your search terms and send yourself any documents you think will be helpful.
