A. Is the information in the source written by an expert in the field?

Explanation:

This is one of the most important factors when it comes to finding a good and reliable source. We should find information about the author, about his previous work, experience and education. It can be helpful to see if it is published by some university or another institution. This is significant because the right to publish permits anyone share their work.

B. Is the source readily available online or in libraries should audiences want to learn more?

Many sources that are not easily accessible, in another words, maybe not all the libraries have that certain book or maybe it is necessary to pay to download it, etc. This factor will not exactly tell us if the source is reliable or not.

C. Is the information in the source relevant to the topic?

Maybe the source gave us knowledge, facts or data that isn't about the topic, but it explains some additional information helping the reader to understand better.

D. Is the information source well-known to the audience?

The source can be published a few days ago and it could be a very good article. Most probably, the audience isn't still familiar with the work just because it is recent.

E. Is the information in the source too technical for audiences to understand?

It is our task to adapt our text, presentation, conference, etc. to the audience we are preparing it for. Imagine that a high school professor is explaining gravity to the students. He may be using some serious and detailed source about physics, that his/her students wouldn't understand on their own, but it is exactly his/her task to adapt the information to the audience.
