Encyclopedia Galactica
A compendium of all knowledge intended for preservation, serving as both a scholarly refuge and a strategic misdirection.
The Encyclopedia Galactica is the name of a number of fictional or hypothetical encyclopedias containing all the knowledge accumulated by a galaxy-spanning civilization, most notably in Isaac Asimov's Foundation series. First appearing in the short story "Foundation" published in Astounding Science Fiction in May 1942, it was originally referred to simply as the Encyclopedia before the term Galactica was adopted for the later fix-up novel released in 1951. However, this public mission served as an act of misdirection; its true purpose was to concentrate knowledgeable scientists on a resource-poor world with the long-term aim of revitalizing the technologically stagnant and scientifically dormant empire. Originally published physically, it later became computerized and subject to continual change.

Lore & Background
In Isaac Asimov's Foundation series, the Encyclopedia Galactica functions as a critical literary device. The author frequently begins book sections or chapters with short extracts from the text acting as epigraphs, which discuss key characters or events to provide the reader with a hazy idea of what is to come. The concept may have been inspired by H.G. Wells's 1933 work The Shape of Things to Come, which features an "Encyclopaedic organization" centered in Barcelona with seventeen million active workers tasked with creating a "Fundamental Knowledge System." Patricio Manns analyzed the text as a paratextual element intended to contextualize the action and bring the trilogy closer to the historical novel. Over time, the physical medium evolved into a computerized database that remained subject to continuous updates as the Foundation grew.
In Their Own Story
The narrative of the Encyclopedia begins in May 1942 with its introduction in Asimov's short story "Foundation." It was initially unnamed, appearing only as the Encyclopedia until the 1951 publication of the fix-up novel. The text describes a massive undertaking on Terminus, where scholars worked to compile every available fact from the Galactic Empire. As the story progresses through the series, these volumes serve as historical anchors. For instance, early chapters open with entries that foreshadow political shifts or character fates. The secret nature of the project is revealed gradually: it was not merely a library but a trap for talent. By concentrating the galaxy's best minds on a resource-poor planet under the guise of preservation, Seldon ensured they would become the nucleus of the First Foundation. As the narrative unfolds, the static physical volumes mentioned in early sections give way to dynamic computerized records that reflect the changing realities of the emerging new empire.
Reader's Guide
For readers exploring the Foundation universe, the Encyclopedia Galactica is essential for understanding the series' structure and themes. It operates as a repository of all knowledge from the Galactic Empire, intended to survive a predicted catastrophe. To engage with it effectively, note its evolution: starting as physical books in 1942 fiction and transitioning to computerized formats later in the timeline. When reading the novels, pay close attention to the epigraphs at the start of chapters; these are direct extracts from the Encyclopedia designed to offer context or foreshadowing. The text serves a dual purpose: it preserves history while simultaneously hiding Seldon's psychohistorical plan to rebuild civilization. Scholars in-universe view it as an objective record, but the reader knows it is a tool for misdirection. Its relevance extends beyond Asimov, appearing in works by Orson Scott Card, Robert A. Heinlein, and Arthur C. Clarke, often cited as the ultimate reference for galactic history.
Did You Know?
- The term 'Encyclopedia Galactica' was not used in the original May 1942 short story; it was first called simply 'the Encyclopedia'.
- Frank Holby used the specific term 'Encyclopedia Galactica' before Asimov did, in his July 1942 story 'The Strange Case of the Missing Hero'.
- H.G. Wells's 1933 book The Shape of Things to Come featured a similar organization with seventeen million active workers centered in Barcelona.
- In Douglas Adams' series, the Hitchhiker's Guide is noted as being cheaper and featuring the words 'DON'T PANIC' on its cover compared to the more pedestrian Encyclopedia Galactica.
- Orson Scott Card set his 1989 story 'The Originist' within Asimov's Foundation universe, mentioning the collection as containing all knowledge of a galactic Empire.
