There is a wealth of resources available for this project. Not only are your instructors available to guide you, but the librarians are also here to assist with finding resources and following the MLA style guide for citations. You can always email them with a question @ library-help@interlochen.org.
Reminder, when accessing our subscription resources off campus, you will reach an EZproxy page and will be asked for a patron ID and pin. Remember to use your student ID # for both. Instructions are here under How to access a database.
As a starting point, your text has many critical sources that should be used.
Bronte, Charlotte. Jane Eyre. 1847. Jane Eyre: An Authoritative Text, Contexts, Criticism, edited by Richard J. Dunn, 3rd ed., Norton, 2001, pp. x-x.
PLEASE NOTE! An outstanding source for critical documents is the JSTOR Understanding Series: Jane Eyre. The JSTOR Understanding series is a research tool from JSTOR Labs that connects primary texts with journal articles and book chapters on JSTOR that cite those texts.
