When gathering resources for your paper, keep track of the information you will need to cite that resource if, in fact, you use it in your paper.
This means, write down the information typically used in a citation, for example, the author(s) name(s), complete title of the resource, publisher, date, etc. Perhaps you can make and keep copies of the first pages of the resource, whether print or electronic, for easy citation later.
The reason for this tip is that if you don't keep good records, you may end up trying to re-locate that resource. Searching over again for something you already found can be a time consuming and frustrating problem!

Each school subject may have a different 'style' of citing that you need to use to justify your argument. Also, you need to cite to show your instructors where you got your evidence.
*Your research includes any speeches, presentations, discussion posts, or papers that you produce using outside sources.
These associations have created styles not only for your citations but also for the formatting and language used in your research papers.
