How to Credit Sources

Using other people’s ideas is a recognized and important part of being a good scholar. It becomes plagiarism only if credit is not given appropriately to the original source. The very same use of other people’s ideas that might be considered plagiarism if the source is not acknowledged is considered good scholarship if attribution is given correctly.
