Here's why:
* References are a list of sources that were *actually cited* in the text of your work. These are the sources you directly referenced to support your arguments or provide evidence.
* Bibliography is a more comprehensive list of sources that you consulted, whether or not you directly cited them in your text. This includes sources that you found helpful for your research but didn't end up using in your paper.
Think of it this way:
* References are like your "Thank you" list for the sources you used directly in your paper.
* Bibliography is like your "Books I Read" list, including those you didn't necessarily use directly in your paper.
In academic writing, it's common to include a "References" section and a "Bibliography" section if you consulted sources that weren't directly cited in your paper.
