I want some help on how to write a literature review -- how to start and end. I just have 3 days and have to write a mini-thesis of 30 pages. Symbolism in Wuthering Heights is my title.

Do you want help with the literature review or the 30-page paper? They are two separate things.

Didn't your instructor teach the class how to do this?

Three days is a horribly short time to do a review and write such a long paper. Did you just get the assignment today? If so, your teacher should be reported to the principle or dean of students.
