Citing information is important and necessary for many reasons and one of them is acknowledgment for who wrote the book/article. To me citing makes your source relevant, and supports what ever work you are doing. People who read your work always want to know where your information came from, It validates your work. because if you do not put where it came from, people will judge your work and may not believe its factual. People also may think you plagiarized your work or copy it because it was not cited. Cite work by posting the web address or you could always use easybib.com, to cite works.
