Citing Your Sources
You are required to identify for your reader which ideas, facts, theories, concepts, etc., are yours and which are derived from the research and thoughts of others. Whether you summarize, paraphrase, or use direct quotes, if it's not your original idea, the source must be acknowledged. The only exception to this rule is information that is considered to be common knowledge [e.g., George Washington was the first president of the United States]. If you are in doubt about whether a fact is common knowledge or not, protect yourself from any allegations of plagiarism and cite it, or ask your professor for clarification.
Use MLA format for your extended essay.
