If you’re trying to figure out how many Warhammer 40K books there are, the short answer is that there is no single fixed total. The setting has been expanding for decades across novels, short-story collections, anthologies, audio dramas, and tie-in series from Black Library.
That means the number changes over time, and it also depends on what you count as a “book.” Here’s a clear guide to the scale of the Warhammer 40K library, how it is organized, and where to start reading.
How many Warhammer 40K books are there?
There are hundreds of Warhammer 40K books, and the total keeps growing. If you include novels, novellas, anthologies, and related fiction, the count is well into the hundreds rather than a neat, closed series total. Because the franchise is ongoing, any exact number becomes outdated quickly.
What counts as a Warhammer 40K “book”?
The answer changes depending on what you include. Some readers mean only full-length novels, while others count every fiction title set in the 41st millennium.
Common categories
- Novels — full-length stories set in the Warhammer 40K universe.
- Novellas — shorter, standalone works or side stories.
- Short-story collections — themed or author-based anthologies.
- Omnibuses — collected editions that gather previously published fiction.
- Series tie-ins — books linked to major factions, campaigns, or characters.
So if someone says “there are 300 Warhammer 40K books,” they may be counting one category and leaving out others. That is why the safest answer is not a single number, but a range: well over 100 and likely several hundred depending on the definition.
Why the total is hard to pin down
Warhammer 40K is not a single novel sequence in the usual sense. It is a shared fictional universe, and Black Library has published fiction across many different sub-series and formats.
The setting is modular
Unlike a tightly ordered saga, Warhammer 40K fiction is built around factions, wars, and characters that can be read in many different ways. One book may focus on Space Marines, another on the Imperial Guard, another on Chaos, and another on alien factions such as the Eldar or Orks.
Publication is ongoing
New titles continue to appear, so any list is temporary. Even a careful count becomes outdated as soon as a new novel, novella, or anthology is released.
Reprints and collections complicate counting
Some stories first appear in magazines, audio form, or limited editions before being collected later. Depending on the counting method, the same story may be treated as one title, one chapter in an anthology, or part of a larger omnibus.
A practical reading guide for Warhammer 40K
If your real question is not just “how many?” but “where should I begin?”, the best approach is to choose a reading path based on your interests. Warhammer 40K can be intimidating at first, but you do not need to read everything to enjoy it.
Good starting points by interest
- For a broad introduction: start with a major entry-point novel or a beginner-friendly series tied to the Imperium.
- For military fiction: look for stories centered on the Astra Militarum, Space Marines, or large-scale campaigns.
- For darker, more investigative stories: consider Inquisition-focused fiction.
- For faction-specific reading: choose books about the faction that interests you most, such as Chaos, Necrons, or Eldar.
Because the universe is so large, a faction-based approach often works better than trying to read in strict publication order. Many readers discover the setting through one character or series and then branch outward from there.
Reading order: do you need one?
Not always. Some Warhammer 40K series reward reading in order, especially when they follow a recurring cast or a long campaign arc. But many novels are designed to stand on their own, or to function as entry points into a larger corner of the setting.
If you want structure, try this simple method:
- Pick one faction or theme that interests you.
- Read one standalone novel or the first book in a known series.
- Move to related novels, novellas, or anthologies if you want more context.
- Only then consider larger crossover events or long-running sub-series.
What makes Warhammer 40K fiction distinctive?
Warhammer 40K books are known for their grimdark tone: a future defined by endless war, institutional decay, religious extremity, and survival against overwhelming odds. The fiction often combines military action with gothic atmosphere, political conflict, and cosmic horror.
Major recurring themes
- War as a permanent condition — conflict is not exceptional; it is the normal state of the universe.
- Faith and fanaticism — belief can be both sustaining and destructive.
- Human fragility — ordinary people often exist under vast, impersonal systems.
- Corruption and entropy — empires, bodies, and ideals all deteriorate.
- Duty versus survival — characters are often trapped between loyalty and self-preservation.
These themes help explain why the library has expanded so successfully. The setting can support detective fiction, war stories, horror, tragedy, and adventure without losing its core identity.
How the books are organized
Warhammer 40K fiction is often grouped by major publishing lines or by character arcs rather than by one master chronology. That can make the universe feel sprawling, but it also makes it flexible for different kinds of readers.
Common reading clusters
- Faction series — books focused on one army or civilization.
- Character-led series — recurring protagonists or antiheroes across multiple titles.
- Event-based books — stories tied to major conflicts in the setting.
- Anthologies — useful for sampling many writers and tones.
Because of this structure, the “number of books” is less important than the shape of the library. There are many entry points, and each one opens into a different part of the same universe.
Best way to choose your first Warhammer 40K book
If you are new to the setting, the best first book is usually the one that matches your taste in genre. Warhammer 40K can be read as action, horror, political fiction, or epic military drama.
Choose based on reading preference
- Want fast-paced action? Choose a military or battle-focused novel.
- Want atmosphere and dread? Try horror-leaning fiction or Inquisition stories.
- Want lore and worldbuilding? Start with a novel that introduces the Imperium clearly.
- Want a long commitment? Pick a major series and read it in order.
A good first Warhammer 40K book should teach you the setting without requiring encyclopedic knowledge. The strongest entry points usually balance clear stakes, vivid worldbuilding, and enough context to make the universe feel coherent.
Quick answer: how many Warhammer 40K books are there?
There are hundreds of Warhammer 40K books, and the exact number depends on whether you count only novels or also novellas, anthologies, omnibuses, and audio fiction. Since the line is still growing, the total is best understood as an expanding library rather than a fixed series.
Final takeaway
If you were hoping for one exact number, the most accurate answer is that Warhammer 40K has far too many books to count as a single closed series. Think of it as a vast, ongoing fiction universe: huge, modular, and best approached by choosing one faction, theme, or series at a time.
