Your first step in doing research will be finding background information on your topic. If you are looking for information on endangered species, one of the most important things you will need is the scientific name of an organism. For example, the scientific name of the red wolf is Canis rufus. An organism may have many common names, but the scientific name is fairly standard in the research literature. You will need to use the scientific name rather than the common name, or perhaps both, to conduct further research.
The resources listed on this page should help you get started with your research.
