There are some book series that just seem to go on forever. They create epic journeys and worlds that feel almost three-dimensional. They take up entire shelves of book cases all by themselves. These are some of the largest and longest running
series in the literary world.
In order to count as one of these a series must meet all of the following conditions:
- Published over the course of at least ten years.
- Contain at least ten books.
- An Expanded Universe is not a series, though there may be series long enough to count inside an Expanded Universe.
