All sources are part of a larger conversation
As you "listen" to the scholarly conversation, you will notice that information sources appear in a wide variety of formats depending on when the information is created. This timing and variety is part of an "information cycle" or timeline. You'll see that each source of information along the timeline offers greater detail about events.
For example, the reference sources you read for background, such as encyclopedias, are often written months or years following an event. This hindsight is a benefit as these articles can provide important background and context, which are important to your understanding of the topic.
As a student coming into the conversation, knowing where along the timeline the information you find falls will help you choose relevant sources.
Let's learn more about the information cycle in the following video...

What happens to the information once an event occurs?
This is the Information Life Cycle Zone
Information starts with an event
For example and alien crashes lands in the remote desert of Nevada.
Moments later, images are posted on social media -- tweets of fear, people may be scared at first.
Later that day, a news crew is on the scene talking to witnesses and checking facts for TV and radio.
News coverage continues in the following days.
People begin to see the alien integrating into human society.
A week or so after the event popular magazines begin to do in depth pieces on the alien.
Given more time, researches begin to publish academic journal articles on very specific topics like
During the year following the event, books and government publications address different topics related to the alien landing like
Years after the first alien landing, reference books like encyclopedias and bibliographies include entries on the event.
What followed and how researchers of different types have studied the aliens.
There may be bibliographies published that bring together lists of all the information published about the alien.
And all this time the conversation never really stopped nor did news stories about the alien in society.
We have reached the end of the information life cycle.
