A Librarian’s Guide to SCIENCE FICTION
A one-stop guide for librarians to navigate the expansive world of science fiction, featuring key characteristics, major subgenres, influential works, and curated resources.
About the Genre
“I write about people who do extraordinary things. It just turned out that it was called science fiction.” – Octavia Butler
Science fiction is a genre centered on “what if” questions, exploring limitless possibilities grounded in science or plausible future developments, where technology or scientific ideas are essential to the story. It stands out as a genre of change. Using elements from many fields, such as social sciences, ethics, religion, and ecology, writers examine complex moral and societal issues in imaginative settings that may feel unfamiliar. While science fiction often struggles to accurately predict the future, as once-futuristic ideas can become everyday realities, its true power lies in inspiring innovation and shaping the future by sparking curiosity and creativity in both readers and scientists.
History of the Genre
There is a lack of consensus when it comes to defining science fiction as a literary genre. Often contested amongst devotees and historians alike, it can be hard to pinpoint its beginning. Nevertheless, it’s hard to argue the impact of some key creators. Watch the video to learn how the genre was shaped over hundreds of years.
“Forget the stereotypes. That is the first thing librarians can do while conducting sf readers’ advisory.”
— Kim Kofmel (2004)
General Readers Vs. Fans
Readers of science fiction often fall into two broad groups: general readers and purists/fans. General readers tend to be curious and open to recommendations. They enjoy series fiction and may develop a strong preference for a particular author whose work resonates with them.
Purists/fans, by contrast, are deeply knowledgeable about the genre and its history. They typically prefer to seek out information independently through reviews, forums, and other readers’ advisory (RA) resources. While they may not rely heavily on direct recommendations, purists can be invaluable to librarians, offering expertise on the genre.
Appeal Characteristics

Pacing is typically shaped by how much action is present. Stories focused on internal elements (like philosophical or psychological) tend to move more slowly but can feel deeply engaging. In contrast, stories driven by external action move quickly and keep readers turning pages through constant excitement.
In science fiction, character development often takes a back seat to the setting and plot. Because many science fiction works are part of a series, authors usually expand and deepen characters over time, especially after establishing the complex world in which the story takes place.
The plot frequently challenges traditional beliefs and explores complex or uncomfortable questions. These stories are often set in the future or in unfamiliar worlds, pushing readers to think in new ways in order to understand the environment. At its core, science fiction highlights the value of storytelling and imagination.
The setting is vivid and highly descriptive, requiring readers to picture the world, characters, and events clearly. The tone can vary widely. It can be humorous and quirky or dark and serious. This strongly influences the overall mood. Attention to detail is especially important, as science fiction often relies on technical and imaginative elements that enrich the experience.

No matter where or when the story takes place, it reflects the issues and concerns of the time it was written. his is important to remember in readers’ advisory because it helps librarians connect readers with books that match their interests.

This video explains that science fiction did not suddenly begin with modern authors like Ray Bradbury or Frank Herbert.
