Fast capture
ISBN scanning, cover photo, OCR and manual editing all live in the same flow.
Personal catalogue
Book42
A tidy archive for physical books, collections, reading progress and shelves. Built local-first, syncs when you need it, and works just as well for volumes without an ISBN.
Why it exists
A personal library, not an inventory spreadsheet
Local-first
Your library stays usable on-device. Cloud and the web dashboard add sync on top.
Collections & series
Volumes, editions, shelves and missing entries are treated as catalogue data, not scattered notes.
Workflow
From shelf to catalogue in a few steps
Scan
ISBN or cover photo from your phone.
Review
Title, authors, edition, reading status.
Organise
Filters, series, shelves and the web dashboard.
