Do more with this book catalog
The UDXIA Classic Science Fiction Archive offers a focused collection of 96 public-domain stories, arranged into four thematic categories. The tools here help you explore that catalog by subject, compare stories side by side, or estimate your reading time before you begin. Each page draws on catalog data to make your browsing more deliberate.
Whether you are drawn to space voyages, strange worlds, social speculation, or machines and inventions, the archive provides a way to find stories that fit your interests. Use the Finder to match subjects, the Compare tool to weigh similar tales, or the Reading page to plan your session. All tools are built from the catalog's own records.

Ways the catalog data becomes useful
Compare Stories
Place two titles side by side to see word count, reading time, sentence complexity, and subject overlap. Useful for choosing between similar-sounding works or planning a themed reading list.
Reading Time Estimates
Each story includes a median-based reading time. Most are quick reads under an hour, with a few longer pieces for immersive sessions. Plan your next break or evening accordingly.
Choosing a Path Through the UDXIA Archive
The UDXIA Classic Science Fiction Archive holds 96 public-domain stories, most of them short enough to finish in a single sitting. With four categories and a median reading time of 37 minutes, the collection invites browsing, but the sheer number of options can still feel open-ended. The three tools on this page — Book Finder, Compare Books, and Reading Tracker — address different moments in that process: narrowing down, weighing two or three candidates, and planning how to actually get through a longer read.
Start with Book Finder when you have a preference but no title
Book Finder is the natural entry point when you know you want a Space Future story or a short read, but you have not settled on a specific work. The catalog's categories are uneven in size — Space Future holds 29 titles, while Other Worlds, Machines Invention, and Social Speculation each hold roughly 22 or 23 — so filtering by category alone can still leave you with a long list. Adding the supplied filters for word count, estimated reading time, chapter rhythm, or sentence flow narrows that list to a manageable handful.
Suppose you are in the mood for a Machines Invention story with a brisk pace. A quick filter on that category and a shorter reading time will surface titles like "Nor Dust Corrupt — Edition Insights," a 39-minute story about wealth, cemeteries, and the death care industry. The Finder does not judge quality, but it does let you match a story's measurable traits to your current appetite.
Use Compare Books when two or three stories look equally appealing
Once Book Finder has produced a shortlist, Compare Books lets you place two or three titles side by side. The comparison shows word count, estimated reading time, text sections, sentence flow, chapter rhythm, and subjects — the same descriptive metrics that appear in the Finder. Seeing them together can clarify a trade-off you might not have noticed from a single record. A story with a lower word count may still have a denser sentence flow, which could make it feel slower than its length suggests.
For example, if you are torn between a 40-minute Space Future tale and a 30-minute Other Worlds story, the comparison will show not only the time difference but also how many text sections each uses. That structural detail can matter more than the raw minutes, especially if you prefer to pause at natural breaks.
Move to Reading Tracker once you have committed to a title
Reading Tracker is for the moment after selection, when you want to turn a chosen story into a concrete plan. It records progress in pages, with a current page, total pages, and a daily page goal. If the catalog does not supply a fixed page count, the tracker estimates one from the word count — dividing by 250 words per page — but you can replace that estimate with the page total from your own reading app or edition.
The tracker does not record sections or minutes as progress, only pages. That simplicity works well for the archive's mostly short works, where a single sitting often suffices. For a longer story such as "The Undetected — Inside the Classic" at 13,541 words, the tracker helps you spread the read across several days without losing your place.
