First, gather all of your print sources, such as books, magazines, and encyclopedias. Decide which ones you are most likely to use. Then,
create a source card for each one by writing the title, author, page
number, and any other important information on an index card. When
you are finished, number each of your source cards. This way, as you
begin to take notes, you can just write the number of the source
instead of writing all of the information again and again.
