Types of Sources: Information Cycle

 

A circle made up of connected arrows. Symbolizing a circle.This page covers:

  • The Information Cycle, which traces when types of information sources become available, what types of information those sources produce, and how information changes over time.

 

What's the point?

Understanding the information cycle will allow you to:

  • Identify what sources will be available for your research topic.
  • Understand the different purposes and context for information based on a source's publication format.
  • Identify and differentiate between popular and scholarly sources.

Lightbulb.Tip: Your assignments will often call for you to use peer reviewed sources in your research. The information cycle lets you know that peer reviewed articles will usually take over a year to publish and you should base your research topic around what sources will be available. If a topic is important to you, remember that you can always try to adapt of broaden your question. If you are unsure if your topic will produce the needed sources, remember that you can ask your professor or a librarian.
