From your inputs to a usable result
01
Explore source-linked editions
Browse 400 editions from a fixed 2025 publisher catalog. Search titles, contributors or ISBN-13, then combine format, section and page-count filters.
02
Compare the guidance for your readers
Enter optional whole-year ages for up to eight labels. Inspect each source range and compare up to six saved editions without treating age matches as reading-level or suitability scores.
03
Keep a practical reading list
Record reading status, your availability and notes for up to eighty editions. Export every saved book as TXT or CSV with source links, or keep a JSON backup of the exact catalog and project.
Before you start
Where is my project saved?
Projects are saved in this browser for this site account. Download a JSON backup before changing devices or clearing browser storage.
Where do the book facts come from?
Titles, ISBNs, contributors, formats, page counts, imprints and age ranges come from the cited Penguin Random House Retail 2025 catalog. Each edition links to its exact catalog page and publisher ISBN page. The app includes factual metadata, not book covers or copied descriptions.
Does an age match mean the book is suitable?
No. It compares entered whole-year ages with publisher guidance. It does not test reading ability or review content. Catalog sections are merchandising groups. Preview the actual edition and make your own choice.
How are missing ages handled?
Blank is unknown, not zero. At least one age needs one included reader in range. Every age needs at least one included reader and no unknown or out-of-range ages. Excluded readers remain in the project.
Are prices or availability current?
No. This is a fixed catalog snapshot checked on 2026-10-23. Owned or available is your own local record. Visit the publisher or your library for current edition details and availability.
Will filters hide books from my export?
No. TXT and CSV include every saved edition in list order, including finished and parked books, all reader labels, personal notes and source links. JSON also preserves the exact catalog snapshot.
Can I resume later?
Reopen the saved project on this browser and account, or restore its JSON backup. Keep backups in a place you trust because they include your supplied material.
