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.

Labs is where the strategic initatives group tests new technologies and services that may be of interest to our members and the broader Crossref community. Some of these experiments graduate and become new Crossref services. Others metamorphosize or are absorbed into existing services. A few languish and die.

In all cases, this is where you can find links and information about the latest projects that Crossref is working on. Please contact us if you have an idea about a new service, feature or industry initiative that you would like to see Crossref explore. You can reach us at:


Have fun.
