Citing has two main purposes:
- To acknowledge your debt to the research and creativity of other people.
- To allow your readers to track down the sources of your evidence, so that they can evaluate and confirm your argument.
It is therefore, important to make a clear distinction between the work of other people, and even your own previous work, the new and unique content of your current assignment. Moreover, to help readers to track down the works that you cite, you should refer to readily available sources whenever possible. You should also provide bibliographical details (the title of paper or book, the volume, the page etc.) in a consistent way, according to one of the accepted styles of citation.
