Finder
Narrow the archive by category, subject, or reading time. The Finder suggests titles that fit your preferences, so you can skip straight to a story you are likely to enjoy.
Do more with this book catalog
The UKOVU Classic Science Fiction Archive holds 90 public-domain stories, mostly short works from the pulp era. They range from Mars adventures to tales of alien contact. Use the tools below to find a story that matches your reading mood, compare two titles side by side, or gauge how long a story will take before you begin.
Each title includes a plain-text edition with details such as word count, estimated reading time, average sentence length, and subject tags. The archive is organised into four categories: Space Future, Other Worlds, Machines Invention, and Social Speculation. Browsing is straightforward, and every story is free to read online.

Ways the catalog data becomes useful
Compare
Place two books side by side to see word count, reading time, sections, and sentence complexity. This helps you choose between similar stories or plan a reading session.
Reading
Check estimated reading minutes based on a median pace. Adjust for your own speed and decide whether a story suits a short break or a longer sit-down.
Starting Points in the UKOVU Science Fiction Archive
With ninety classic science fiction titles spread across four categories, the archive can feel larger than it is. The median book runs about 9,500 words, so most selections are short enough to finish in an evening. The three tools on this page — Book Finder, Compare Books, and Reading Tracker — work together to turn that abundance into a manageable reading plan.
Choosing with Book Finder
Book Finder narrows the catalog by category, length, estimated reading time, chapter rhythm, sentence flow, and subject. If you want a Mars story, the subject list includes ten titles set on the planet, and the category filter for Space Future covers forty-two books. The tool lets you combine these signals, so you might ask for a short Space Future title about Mars and get a list that includes Young Man from Elsewhen — Reading Companion, a 8,195-word time-travel story that also touches on California and railroad travel.
A useful habit is to start with one firm criterion — a category or a subject — and leave the other fields open. The catalog is small enough that a single filter often returns a handful of titles, and you can scan those quickly. The no-preference options do not penalize a book, so you can experiment without worrying about missing a hidden gem.
Refining with Compare Books
Once you have two or three candidates from Book Finder, Compare Books lays out their measurable differences side by side. Word count, estimated reading time, text sections, sentence flow, and chapter rhythm appear together, which helps you see whether a book will feel like a quick interlude or a longer commitment. For example, The Dancers — Edition Insights runs 4,628 words and reads in about 21 minutes, while The Lost Tribes of Venus — Background and Themes takes 110 minutes. Knowing that before you start can shape when you choose to read it.
The comparison is not a judgment of quality. A higher word count does not make a story better, and a shorter one is not lesser. The value is practical: you can match a book to the time you have, or pair a dense, sentence-heavy story with a lighter one for variety.
Planning with Reading Tracker
Reading Tracker turns a chosen book into a concrete plan. It records your current page, total pages, and a daily page goal. If the catalog does not provide an official page count, the tracker estimates one by dividing the word count by 250. You can replace that estimate with the page total from your own reading app or edition, which is useful when you are working from a print copy.
The tracker also estimates remaining time and finish days based on your daily goal. For a book like The Rhizoid Kill — Reading Notes, with 7,479 words and an estimated 33 minutes of reading time, a 20-page daily goal would finish it in a few days. The history is stored in your browser, so you can return to it without an account.
Using the tools together
The three tools support a single workflow: find a few candidates, compare them to decide, then track your progress. Starting with Book Finder and moving to Compare Books is natural, but you can also use the tracker to set a goal and let that guide your choice. The tools do not rate literary quality; they help you navigate the collection on your own terms.
