Church History Timeline
The Puritan section from Clay McKinney's ordered list of significant events in church history.
The Still Waters Revival Collection
Here you'll find a generous selection of articles and tracts from the Reformers and Puritans. This is the best source I have found on the Web for writings from John Knox. The modern controversial works featured here are not so helpful, but if you can separate the gold from the dross, there are some fine, and rare, Puritan works at the Still Waters site.
Foxe's Book of Martyrs
The indispensable Puritan work on the history of martyrdomwith particularly graphic accounts of Catholic atrocities.
A Puritan's Mind
This site features Puritan bios, Puritan writings, Puritan Creedsplus articles on theological issues, T-shirts, and more. There's material from Turretin, Ames, and Christopher Loveall quite good.
