The term self-concept is a general term used to refer to how someone thinks about, evaluates or perceives themselves. To be aware of oneself is to have a concept of oneself.
The specific aspect of literary criticism that demonstrates the author's message as significant or worthwhile is the author-based approach. It is also called the Expressive Theory. It depicts that the best interpretation of a text (poem, novel, fictional stories, etc) comes from the author himself.
The reader-based approach is not entirely reliable because every reader may see a text in a different perspective. There are even cases wherein readers interpret a text in a deep, deep way while the author meant everything in the literal sense. Everything varies from case to case.
You should look at web sources that have recently been updated because a lot of times new information is present that could change the original point/evidence. This could discredit the source. You also should do this because the newer the information, the more credible it is in the time (older information could easily be outdated).
