Why do I need to cite a source?

Citations indicate which ideas are taken from others and from whom those ideas were taken; in other words, they give credit where credit is due. Citations allow researchers to find, read and comment on each others' sources.

What are Citations? from the University of Minnesota Libraries

If you use, quote, paraphrase, summarize, or otherwise refer to the work of others, you need to cite the source of that information. This will allow the reader to locate the work (e.g. article, book, website, image, film, etc.) to which you are referring and help you avoid plagiarism.

Citation tools and database features

  • Many databases (like Academic Search Premier, search on library homepage, Google Scholar) offer the option of creating your references in common style. Look for this as you save, e-mail or print your references. 
  • Tools including Mendeley, Zotero, and EndNote help you to save and organize your PDFs and references, create bibliographies, and create in-text citation with word-processing software (like Microsoft Word or Google docs) in hundreds of styles.

What is an annotated bibliography?

An annotated bibliography, in addition to all of the citation information for a source, also includes descriptive and critical information about the source. The purpose of the annotation is to inform the reader of the relevance and quality of the sources.
