Mungo Park's Travels in the Interior Districts of Africa was published in 1799 and is one of the very few books from that time still in print. Very popular in the nineteenth century, it was published in many English editions as well as German, French, Swedish and Dutch.
Here is an edition from 1821. It is one of three I know of published in the 1820s in Dublin by three different publishers. All are small (129 mm x 82 mm; 5.1" x 3.2") and cheap editions with poor printing and reproduction of the woodcuts.
