Destacando nuestra comunidad en Colombia

English version

Dado que Crossref celebra su 25º aniversario este año, nos gustaría destacar algunas de las regiones activas y comprometidas en nuestra comunidad global.

Durante los primeros 25 años, la composición de los miembros de Crossref ha evolucionado significativamente. De un puñado de grandes editoriales fundadoras, ahora tenemos más de 22.000 miembros de 160 países. Casi dos tercios de ellos se identifican como universidades, bibliotecas, entidades gubernamentales, fundaciones, editoriales académicas, e institutos de investigación.

Notice of amendments to Crossref membership terms and bylaws

In its March 2025 meeting, the Crossref board unanimously voted to update both the Crossref bylaws and the Crossref membership terms to:

  • Provide more clarity and alignment between our bylaws and membership terms, where they had become out of sync over the years.

  • Reflect previous board motions and bring both documents up-to-date with current processes for suspending and revoking membership, and reviewing those decisions.

  • Work towards being more explicit about what “Member Practices” should look like in terms of preserving the integrity of the scholarly record.

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.

InChI Lookup

 2 minute read.
Note: This experiment has been retired. This description has been kept for reference, but many of the links and/or services that appear below no longer work.

The idea is to create a mechanism that would allow Crossref publishers to record InChIs in their submitted Crossref metadata. This, in turn, would allow us to provide a service that would allow users to:

  • Lookup the published articles that mention a particular InChI.
  • Lookup the InChIs mentioned in a published article.

Similar services could, conceivably, be provided for other types of semantic metadata.

The following is a demonstrator of what an DOI2InChI lookup service might look like. Please note that the XML representation of the results is very basic and is not best-practice for linked-data.

The demonstrator currently only holds DOIs and InChIs for a few publishers. A summary of the contents of the database can be found on the status page

http://inchi.crossref.org.turing.library.northwestern.edu/status

A list of all the Crossref DOIs that contain InChIs can be seen here:

http://inchi.crossref.org.turing.library.northwestern.edu/dois

A list of all the InChIs that have been registered with Crossref can be seen here:

http://inchi.crossref.org.turing.library.northwestern.edu/inchis

The system provides the following API calls:

Return all the DOIs that have been registered with a given InChI

http://inchi.crossref.org.turing.library.northwestern.edu/dois/InChI=1S/C4H6O2/c1-3-6-4(2)5/h3H,1H2,2H3

Return all the InChIs that have been registered for a given DOI
