Hey...I decided to try something a bit new (at least for me) for my last paper.  I tried to create links within the paper, since it was submitted electronically and I am guessing that most of the readings will be done electronically.  It should provide links to documents online and in a companion folder that I uploaded to GoogleDocs.  I wonder if anyone else has done the same?  Is this the future of how documentation will be completed for online journals?  it seems to provide a greater intertextuality, but also could be quite cumbersome and almost overwhelming.
