School Policy on Wikipedia: Read for background but do not cite!
Rule No. 1: Use Wikipedia as a starting point for your research, but don't cite it unless you can exhaustively demonstrate that is is the only authoritative source on a particular issue.
Rule No. 2: Re: Rule No. 1: That doesn't mean that you should use the information from Wikipedia anyway and just not cite it. It means that you should find other research sources. Encyclopedias are only meant as starting points! For example, you could find the bibliography in the Wikipedia article and look at the sources that the author of the article used. You could also look to see if there is a list of links. Check those out as well.
Rule No. 3: If you are unsure, ask your teacher or librarian!
You will follow the instructions given on the page IMAGES for citing images. You should use the images you find in Britannica before you go to a GOOGLE search. This way you can ensure that you have the information necessary to cite the image.
This can be referenced by creating a hyperlink on the page to the source of your information. since you will submit an electronic copy of your work, your teacher will then be able to go to the site from which you took the infomration. If you do not know how to do this, watch the YouTube video below.
