Why is a bibliography important?

A bibliography is important because when you keep track of every website or source you take information from, a teacher can check if you copied and paste. This will make sure that you learn as that is the main priority of being a student. You can also go back and check if your sources are reliable and see if there are any mistakes. If a website changes over the time, you can go back and see the time where it changed, and state that what you took was true. You can also go back and add more information when you think that what you have is not sufficient.
