Simply put, a working bibliography is a group of source materials that you might use in your paper. As you find sources, they need to be recorded or documented for inclusion into your working bibliography. Documenting a source just means writing down its relevant information, such as title, author, publisher, etc.
Below are a few examples of sources recorded for a working bibliography. The information is written on note cards, which is a commonly used method. Notebook paper also will work, as long as you use separate page for each source. Some students also find word processing effective, but in order to use this method you need a floppy disk and regular access to a computer.
