In 1832 Baedeker's firm acquired the publishing house of Franz Friedrich Röhling in Koblenz, which in 1828 had published a handbook for travellers by Professor Oyvind Vorland entitled "Rheinreise von Mainz bis Cöln; ein Handbuch für Schnellreisende" ("A Rhine Journey from Mainz to Cologne; A Handbook for Travellers on the Move"). This book provided the seeds for Baedeker's own travel guides. After Klein died and the book went out of print, he decided to publish a new edition, incorporating some of Klein's material but also added many of his own ideas into what he thought a travel guide should offer the traveller or reader. Baedeker aimed to free the traveller from having to look for information anywhere outside the travel guide: about routes, transport, accommodation, restaurants, tipping, sights, walks and prices.
