Frequently asked questions
What counts as a "book" in the count?
Numbered novels in the main series. Novellas, short stories, and side-collection volumes are usually excluded unless the author treats them as part of the main count. The book count comes from the canonical series listing, refreshed periodically.
Are these all the longest fantasy series ever?
No — only the longest series in the Novel Nimbus catalog that are also fully complete. A 30-book series that's still ongoing won't appear; once its final book lands, it will. The catalog is a curated subset, not exhaustive.
Do these have audiobooks?
Most do. For a list ranked specifically by audiobook listening time (instead of book count), see "Longest by Audio." Per-series pages show audiobook availability alongside the page count.
Are these the best long fantasy series?
Not exactly — this is "most books" by count, not "best." Genre-specific lists give better quality-curated recommendations within a niche.
