I have to write a 6 page research paper on the purpose of literature. I believe literature is meant to inform us of past experiences in history. I am having a problem finding academic sources for this. Please help! Thank you.

Have you been to a public or college library and asked a reference librarian for help with this? If not, why not? Most academic journals that will be what you want are on databases that the library subscribes to.

Here are two web sites that might help you organize your thinking --

The Purpose of Literature

I have tried everything. But it is quite difficult to find resources for a topic like this.

I appreciate your help but none of those sources talk about the purpose of literature.

I don't know what you were reading, but I sure found info in those links on the purpose of literature including how literature explains historical events.
