I'm at Bristol, England today doing research at Bristol Baptist College, founded in 1679. This school is a gem for scholars interested in Baptist history and thought. Although small, in terms of the number of students who attend, BBC has an amazing archive with manuscripts dating back to the 18th century. You can, for instance, look at a collection of original letters from John Newton (Amazing Grace) to John Ryland Jr. One of the archivists told me that the school a few years ago sold a Gutenberg Bible for close to two million pounds. The school simply couldn't afford to insure the book.
I hope the material I have collected will be helpful as I continue to research and write on 18th-century evangelicalism.
