Continuities are separate continuous series of stories in which events from one work continue directly into another. For example, The Time Machine: An Invention is considered by this wiki to be part of the same continuity as The Time Ships, as that story continues right where the original novel left off. However, many novel sequels are written by different authors, and as such, often contradict each other. These are still taken to be part of the same continuity because they continue events from the original novel. Discrepancies between stories may be attributed to separate Timelines.
Besides the continuities listed in this category, there are also a number of stories which have their own continuity which has never been continued beyond a single story. Some of these are:
- The Time Machine (1949 Production)
- The Time Machine (1978 Film)
- The Time Machine: Trapped in Time
- Time Kid
