There is a new website devoted to the Puritans,
Meet the Puritans. I encourage you to check it out.
The purpose of this website is to promote the seventeenth century English Puritans. We intend to do this by means of original research, theological and devotional commentary upon the writings of the Puritans, reviews of books about the Puritans, recommendations of books about the Puritans, and by providing Recommended Reading of helpful materials in your study of the Puritans.
I would begin with Joel Beeke's excellent article, "Why You Should Read the Puritans," which can be read
here.
