Take good notes while you are researching your information. Always write your notes with accompanying source information. It is a good practice to write the source information with your notes the way you are going to present the information on your bibliography page. If you don't have time to do that, at least make sure you give a quick reference within your notes so you can go back and get the rest of the information when it is time to write the bibliography page.
Clearly separate your source information within your notes so there is no confusion on what information came from each resource.
Read the information thoroughly and then paraphrase it. After reading the information, write your understanding of the information in your own words without looking at the text you got the information from. After paraphrasing the information, compare your written work with the actual text. If it is too alike, reword you information, otherwise it will be considered plagiarism.
Use several different sources when you do your research. This will give you a well-rounded approach to the information and make it less likely that your document will resemble another person's work.
Use in-text citations when using paraphrased information as well as when you are using direct quotes. If there is a lot of information to cite, or if you are instructed to do so, use footnotes. Even when you use in-text citations and footnotes, you are still required to provide a bibliography/references page at the end of your document. You must cite all information that came from another source.
Follow the recommended format style for your in-text citations and bibliography page entries. The most commonly used formats are from the Modern Language Association (MLA) and the American Psychological Association (APA), but you should ask your instructor or employer which format should be used.
