You'll want to decide with your group of researchers what area of expertise you'll want to gain.  Below is a series of links that will lead you into the worlds of the authors you've read and will be studying.  When you find information that is important to you, email your partner with you findings. 

William Wordsworth

From there examine some links to other Web Sites that give information on the Romantic Movement.

(http://landow.stg.brown.edu/victorian/decadence/wilde/wildeov.html).  If you have time, visit Oscar's alma mater Magdalen College in Oxford. (http://www.magd.ox.ac.uk/).

Mary Shelley

  Read about the life of Mary Shelley. (http://www.desert-fairy.com/life.shtml).  She is the daughter of an equally famous woman, Mary Wollstonecraft.  Reading about her mother's life and work may bring illumination to your reading of the novel.  (http://www.desert-fairy.com/feminist.shtml).  You may want to look instead at the literary sources of the novel.  (http://www.desert-fairy.com/franken.shtml).  If you do that, you'll most definitely want to read some of Paradise Lost (gopher://wiretap.spies.com/00/Library/Classic/parlost.txt) by John Milton.  This 17th century poem is the central allusion of  Frankenstein.
