hi
the theme of my dissertation is dualism in the presentation of Hemingway's female characters. i am looking for those people who may guide me how to start and deal with the subject. i fin my self inexperienced in the field of research and looking for guidance(up)

Is this a dissertation at undergradate level, or postgrad? I think the best guide would be your supervisor. There are plenty of books you can get on the subject, so I'd recommend having a search on Amazon or a similar site.
