This subject guide covers resources available at NUS Libraries for Computing

Citing & Plagiarism

Why Cite?

  • To provide evidence for your arguments and adds credibility to your work. It shows that you have sought out and considered a variety of viewpoints on a given topic.
  • To help readers find your sources. It allows them to go through some of the steps you took to reach your conclusions.
  • To show your supervisor(s) the work that you have done.
  • To avoid plagiarism*.

What kind of sources should you cite?

  • Direct quotations from a book, article, film, letter, email, lecture, etc.
  • Ideas you draw from a source but present entirely in your own words.
  • Paraphrases and summaries of books, journal articles, pamphlets.
  • Single words, short phrases, sentences and longer passages quoted from books or articles used.
  • Statistics.

Reference Management Software

The main functions of a reference management software (also known as citation manager or reference manager or citation software or bibliographic management tool) are:

  • Stores and organises references from many sources (e.g. databases, library catalogues and search engines)
  • Inserts these references into a document
  • Formats your references automatically according to a predefined citation style

NUS Libraries conduct tutorials on how to use Zotero and EndNote effectively every semester. Watch out for NUS Libraries' newsletter.


Zotero is a free bibliographic citation management software that allows you to save, collect, manage, cite, and share research sources.

Zotero is available either as a Firefox extension or as standalone software that works with Firefox, Chrome and Safari browsers. It works right in your browser, making it easy to save you citations while you search. Use the Zotero word processor plugins to easily cite your sources and create a bibliography while you work. For further details, please refer to Zotero guide.


EndNote is a desktop-based reference manager, complimented with a web-based version called EndNote Basic.  It has over 6000 citation styles that can be used via Cite While You Write (CWYW) in word processing application.
