About Shelfmark

Shelfmark answers one question well: “In what order should I read this series?” — and then lets you tick books off as you go, without creating an account.

Methodology

Our series and reading-order data is built from Wikidata (CC0) series relationships and ordinals, cross-checked with Open Library records. We list publication order by default — the order most authors intend. Spotted an error? Email contact@zalize.com and we'll fix it.

Privacy-first tracking

Your reading progress is stored in your browser's localStorage only. We run no ad trackers and set no cookies; our analytics is a first-party, cookie-less page counter.
