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.

XML query results and errors

Query results may be requested in three different formats: XSD_XML, UNIXREF, and UNIXSD.

UNIXSD is the recommended and most robust format, but XSD_XML is the default for many services for legacy reasons.

Possible errors returned by malformed or insufficient queries include:

  • an invalid XML query will return no result (<body/>)
  • either first page or author must be supplied
  • either ISSN or journal title must be supplied
  • unreasonable DOI found (an unreasonable DOI does not follow the expected DOI format (10.XXXX/yyy...) and/or exceeds 200 characters)
  • either ISSN/ISBN or series/volume title must be supplied.
