Freud's Psychoanalytic Theory - any good resources?

I'm doing my literary theory essay on psychoanalysis.
I was wondering if anybody could recommend any online resources I could use.
Bear in mind my major is English Literature so I'm clueless when it comes to psychology.
Anything would help, dumbed down or not. Extensive would be useful since I need to apply it to a close reading of a book I chose.

Thank you!
