Retraction Watch retractions now in the Crossref API

Retractions and corrections from Retraction Watch are now available in Crossref’s REST API. Back in September 2023, we announced the acquisition of the Retraction Watch database with an ongoing shared service.

Our aim has always been to better integrate these retractions with our existing metadata, and today we’ve met that goal. This is the first time we have supplemented our metadata with a third-party data source.

Instead, these decisions usually depend on weighing multiple factors based on your particular circumstances. This is true not only for metadata matching, but for many technical choices that require navigating trade-offs.

In this post, we will give an update on our roadmap, including what is completed, underway, and up next, and a bit about what’s paused and why.

Warnings, Caveats and Weasel Words

Most of the experiments linked to here are running on R&D equipment in a non-production environment. They may disappear without warning and/or perform erratically. If one of them isn’t working for some reason, come back later and try again.
