While not directly related to JA's works, I was wondering if anyone knew where to find information on the form of handwriting used in the late-18th C and early-19th C.

It isn't directly related to JA and her works, unfortunately. So, unless someone can make it directly relevant (perhaps discussing JA's own handwriting, or something similar), it should not be on this board. However, there are two options open to those who would like to discuss it without the JA connection. The first is to take it to e-mail. Sarah Cecilia has provided hers, so just click on her name to contact her. The second option is to take it to the Dregston Chronicle Board. The link below will take you to the bridge between Pemberley and Dregston, if you'd like to start a conversation over there.
