Dr. Haykin has written an excellent introductory article to Hercules Collins that was first published in the Evangelical Times in February, 2001. It is also included as chapter 1 in the recently released A Cloud of Witnesses: Calvinistic Baptists in the 18th Century. The text of this article is available online by clicking here. It is also available at Dr. Haykin’s excellent website Fontes – The Writings of Michael A. G. Haykin by clicking here. Additionally, Dr. Haykin also wrote the article about Hercules Collins in the Oxford Dictionary of National Biography. You might want to take a look at it if you have access to that volume.
