You will need to have your own personal copy for annotation of the following works by F. M. Dostoevsky.
The Norton Critical editions offer interesting commentary for further study. Excellent recent translators include our own Prof. Michael Katz and Richard Peaver and Larissa Volokhonsky. Note that there are several titles for the novel known as The Devils (Demons, Possessed). Electronic texts of some novels are also available.
I recommend you purchase the first text from the college bookstore. The other texts (and you may purchase any edition) may be purchased inexpensively using the internet. The best selection was offered by www.amazon.com
