The main part of a Post Office/Kelly's County Directory listed the towns and villages in alphabetical order, with a description of each, later with details of the public institutions for the larger towns, followed by a list of the gentry, etc., (i.e. the well-to-do i the larger houses) in alphabetical order and a separate list of trades people, again in alphabetical order. If this was all, and you were looking for somebody by name, or with a particular trade, but did not know where they were in Hertfordshire, you would need to look at every town/village entry to find them. For this reason there was a Court Directory which listed all the gentry and a trades directory which lists traders alphabetically under trade headings.
