Where can I find "The Three Motives of Raskolnikov" and "Traditional Symbolism in Crime and Punishment" online

I have to write an essay about "The Three Motives of Raskolnikov" by Maurice Beebe and "Traditional Symbolism in Crime and Punishment" by George Gibian. Each of THOSE essays are in the back of our Crime and Punishment book, but I can't find mine anywhere. So does anyone know where I can find these essays to read online?
