Perry Rhodan

The series presents an ongoing chronology - initially beginning 1961 with the (then ten years into the future) 1971 landing by Perry Rhodan and his crew on the Moon and their meeting with the superior but crashlanded humanoid Arkonides. It is augmented with many additional tales that were published in books and spin-off magazines. In addition, the original novellas were adapted in different ways and translated into several languages: the title numbering tries to stick to the internal chronology with the whole numbers reserved for the original novellas. The adaptations and additional tales were put in between. Note that not all of the augmenting titles can be dated exactly regarding the internal chronology.
