When finding my sources, I searched through the Longwood library online site looking for what causes coral bleaching. For each paper I found I would read the title and see if it was relevant to my topic of coral bleaching. I would also read the abstracts of each paper. The only problem I ran into was that their were papers that talked about how coral bleaching affected the assorted fish that lived in coral reefs. This is something I am not researching. All together it was pretty easy to find sources on coral bleaching because it is such a worldwide phenomenon, and there was a lot of information given in the abstracts of each paper I found.
