# Additional Information
## Documenting Your Sources
### Introduction

When communicating information, the writer often finds it necessary to incorporate outside information into a document. This outside information must be credible and factual. There are several reasons why a writer might use outside sources within their documents:
* To clarify information the writer has provided
* To emphasize a point made by the writer
* To prove that an idea has merit
* To acknowledge people who have contributed to your project
* To illustrate how your research contributes to new knowledge and ideas

### Choose a Format

A wide variety of documentation styles exist. Because no one style is suitable for every type of document, the circumstances of a document dictate which style should be chosen. Most organizations state which documentation style should be used by their employees. If you are writing a document for a different organization, find out which documentation style they prefer, and use it. Many organizations develop style guidelines which include sample reports and documents. Citation preference should be found within these guidelines. Conversely, other organizations choose their documents to be cited using a professionally developed system such as APA or MLA. A little research must be done by the writer to determine the preferred style.

### Decide Where to Place In-Text Citations

When using in-text citations, both MLA and APA styles place the author's name in parentheses following the borrowed information. The APA style includes the year of publication along with the author's name. This in-text citation directs the reader to an alphabetized bibliography found at the back of the document. The bibliography styles for APA and MLA are different, but the in-text citations are relatively the same. In-text citations are used to inform the reader where the information being provided is coming from. This is simple when the citation is relevant to a single piece of information such as a quotation or a fact. However, if the citation is relevant to multiple ideas, the citation should be placed in the topic sentence of the information. The author's name may also be used in subsequent sentences to help further aid the reader in determining the initial author of the information being provided.

### APA In-Text Citations

When doing an APA in-text citation, place the author's name and the date of publication behind the pertinent information being cited. This enclosure should be placed inside normal punctuation. Furthermore, a comma should be placed between the author's last name and the date of publication. When citing a specific page, use p. When citing more than one page, use pp. For example, When two molecules approach, they attract or repel each other (Wade, 2006, p. 61). If the author's name is included within the quotation, only include the date and page number in the citation.
