References must be identified within the text of your paper anywhere another author's work or ideas were used. This includes both word for word quotes and summaries (or paraphrasing) of ideas used to support your thesis.
Enter the author's last name, the year of publication for the work--you can find this in the front of the book, next to the copyright symbol--from which the idea or quote is taken, and the page number in parentheses at the end of the sentence.
Repeat these steps in each place of the research paper where another author's work is used or cited.
At the end of your paper, you will be required to include a bibliography, which is essentially a references page that includes a full citation for every work cited within the text. These are listed alphabetically and include the author's full name (last name first), title of the work, the place of publication, name of the publisher and year of publication. Again, this information is generally found in the front of the book. Here is a fictional example:
Short, Matthew. An Early History of Easter Egg Hunts. Parsippany, NJ: Short Publishing, 1982.
