Why Should We Evaluate Sources?

There are many different types of sources out there! Library databases index articles published by scholarly journals, articles published by newspapers and magazines, video clips, book reviews, and much more. Finding a source is only half the battle. Once you find it, you have to evaluate it to make sure it is the best source for your topic. You can evaluate your sources by asking the questions below.

SIFT method for evaluating resources

SIFT is a series of actions you can take to determine the validity and reliability of claims and sources on the web.

The SIFT method, or strategy, is quick and simple and can be applied to various kinds of online content: news articles, scholarly articles, social media posts, videos, images, etc.

Each letter in SIFT corresponds to one of the Four Moves:
