The Hertfordshire Records Society selects important manuscript records and transcribes them. While each volume may only deal with a limited area it is selected as a good example of that kind of document - and may often include information which is not available from other sources. Members of the society get copies of the books as part of their subscription, and many of the older books are available to non-member at a bargin price of £6.00 a volume. I have just updated my web page on the Society and its publications and posted reviews on the two most recent publications

The is a long introduction which look at who Elizabeth Dimsdale was - and what the book tells us about her life and social contacts.
Humphry Repton was a landscape gardener whose red books described his design of a new estate - and this volume contains reproductions of his proposals for developing the landscape around the houses of Panshanger (Hertingfordbury) and Tewn Waters (Tewin).
