Recall that as we discussed earlier, information is written from a perspective; it costs resources to be published; and exists within a legal framework. Sources are produced by people and organizations for particular purposes, and to meet the needs and interests of a specific audience.
When you do research, you use search strategies to discover sources that could be relevant to your topic. Generally you will find more sources than you need. To determine which are the best ones to use, you will need to evaluate the author's perspective and consider the intended audience of the source. Here are some questions that can help you do this:
Both of these articles are written about the same topic - what musicians wear to audition. However, they are written for different audiences with different purposes, and are published in different outlets.
Read each of the articles. How are they similar, or different? What can you find out about the authorship, audience and publication in which each article appears?
Based on what you've learned, in what situations would you want to use either of these sources?
