A "bibliography" or list of references, on the other hand, should never be included at the conclusion of a professional note. You should number your pages. When replying to your memo with questions and comments, including page numbers makes it easy for the reader to refer to the text. Finish with a last paragraph. Include a sentence summarizing the information contained in the memo. References are important tools for verifying information found in books or articles and they are usually needed when writing papers. Including references is the correct way to indicate that you have used other sources in your work. They are also useful when trying to verify information given by others (such as in interviews) or provide further information on topics discussed in the paper. Including references is fairly straightforward. You just need to follow these steps: 1 identify the source, 2 find out what type of reference it is (e.g., author-date), 3 determine how to format it (see next section). References can be placed in either the body of the paper or at the end. If you place them in the body, use footnotes instead if they are too many. End notes are considered poor practice by some scholars because it can confuse the readers if there are extensive notes at the end of the paper. The first thing to do when including references is to identify the source. This means finding out the name of the book, article, or person you are using as evidence.
