The previous German editions had four main sections: "Background", "Tours", "Destinations from A to Z" and "Practical Information from A to Z". MairDumont added a fifth section in each guidebook entitled ""Erleben und Geniessen"" ("Experience and Enjoy"). These new Baedeker guides were the first such guidebooks to incorporate infographics. From the outset, Karl Baedeker recognised the importance of publishing his guides in English as well.

Baedeker in English, the handbook on "The Rhine" (from Switzerland to Holland), a guide in German on Italy ("Ober-Italien"), the first of a series on Italy, which his father had planned and one in French, also on Italy ("Italie septentrionale"). Ernst Baedeker died unexpectedly on 23 July 1861 of sunstroke in Egypt and his younger brother, Karl, assumed charge of the publishing house. 1861−1877: Karl Baedeker II (1837−1911) continued the work started by his brother Ernst. In addition to the ongoing revision of existing guides, he published 14 new guides: four in German, seven in English and three in French. viz.
