As well as county maps you can also collect early road maps. All the county maps of the British Isles up until the reign of Charles II did not show any roads. But in 1675 John Ogilby published his Britannia which was an atlas of 100 road maps of England and Wales. None of Scotland. This must have been a most time consuming and exhausting survey. But it meant that after this period county map started to include roads. Britannia was a heavy folio sized volume. Very difficult to carry around with you. But after 1700 there started to be published a number of smaller atlases with road maps based on Ogilby's survey. Much more convenient for the traveller.
