- On the Bibliography Information cards, FORM 2, we write information about each source that we use. 
- Each time we find a book or any source, we write the title, author, and publishers on one of these cards. 
- On the Source # line we write a number. 
- We write that same source number on each note from that source.
- When we find another source, we fill out a new FORM 2 Bibliography Card, and we give it the Source # that we use on note cards.
