Do more with this book catalog
Explore the AJUZU Classic Science Fiction Archive, a focused collection of 93 public-domain stories from the genre's early decades. The archive is organized into four categories—Space Future, Other Worlds, Machines Invention, and Social Speculation—so you can browse by theme or setting. Whether you're new to classic SF or revisiting familiar authors, the tools here help you find stories that match your interests and reading time.
Each title in the catalog includes practical details: word count, estimated reading time, and subject headings. The median story is about 8,600 words, which means most can be read in a single sitting. Use the cards below to jump into browsing, comparing, or planning your next read.

Ways the catalog data becomes useful
Compare Stories Side by Side
See how two stories stack up in terms of length, reading time, and sentence complexity. This is useful when you're trying to decide between a few options or want to understand the range of styles in the archive.
Estimate Reading Time
Every story includes a reading time estimate based on its word count and typical reading speed. Use this to plan your reading session, whether you have twenty minutes or an hour to spare.
Using the AJUZU Classic Science Fiction Tools Together
The AJUZU Classic Science Fiction Archive holds 93 works, nearly all of them short enough to finish in a single sitting. With 89 titles marked as quick reads and the median story running about 38 minutes, the collection is built for browsing. The challenge is not finding something to read but deciding which of the four categories—Other Worlds, Space Future, Social Speculation, or Machines Invention—matches your mood.
The hub links three tools: Book Finder, Compare Books, and Reading Tracker. Each serves a distinct purpose, but they work best in sequence. Start with the Finder to narrow the field, use Compare to weigh two or three finalists, and then set up the Tracker to pace your reading. Consider a title like "Beware the Star Gods — Reading Notes" (id 298): it sits in Space Future, runs 34 minutes, and has a single text section. The Finder can surface it, Compare can show how it differs from a longer story, and the Tracker can help you finish it in one or two sessions.
Choosing With the Finder
Book Finder lets you filter by category, length, reading time, chapter rhythm, sentence flow, and subjects. Because the catalog is small, you can be precise. If you want a Space Future story about human-alien encounters, the Finder will return a manageable list. You can also use the no-preference option to keep the pool broad; no choice is penalized.
A useful approach is to start with a category and a subject that interest you, then look at the length and time filters. The catalog has 32 Other Worlds and 31 Space Future titles, so those categories give you room to explore. Social Speculation and Machines Invention each have 15, which might be perfect when you want a tighter set of options.
Comparing Finalists
Once the Finder narrows your list, Compare Books lets you put two or three side by side. You can see word count, estimated reading time, text sections, sentence flow, chapter rhythm, subjects, and page information when available. This is where the numbers become meaningful. For instance, a 7,000-word story with a single section might feel like a sprint, while a 20,000-word story with three sections offers natural stopping points.
Compare does not rate quality. It simply shows measurable differences. A longer story is not better, just more of a commitment. A higher average sentence length does not mean a story is harder—it might just have a more formal rhythm. Use the tool to decide which story fits your available time and reading style.
When you are torn between two titles, Compare can settle it. Look at the reading minutes: a 33-minute story and a 46-minute story are both quick, but one might fit a lunch break better. Text sections also matter. A single-section story must be read in one go unless you set your own break, while a multi-section story gives you natural pauses.
Tracking Progress
Reading Tracker records progress in pages, not minutes or sections. You set a current page, a total page count, and a daily page goal. If the catalog does not provide a fixed page count, the tool estimates it as ceil(word_count / 250). For "Beware the Star Gods — Reading Notes," with 7,635 words, that gives about 31 pages. You can replace that with the page count from your own reading app or edition.
The tracker then estimates remaining time and finish days. If you set a goal of 20 pages a day, a 31-page story would finish in about two days. The progress history stays in your browser's localStorage, so no account is needed. You can start a book, pause, and return without losing your place.
