If you are reading this blog on our website, you may have noticed that alongside each post we now list a Crossref DOI link, which was not the case a few months ago (though we have retroactively added DOIs to all older posts too). You can find the persistent link for this post right above this paragraph. Go on, click on it, we’ll wait.
If you take a peek at our blog, you’ll notice that metadata and community are the most frequently used categories. This is not a coincidence – community is central to everything we do at Crossref. Our first-ever Metadata Sprint was a natural step in strengthening both. Cue fanfare!. And what better way of celebrating 25 years of Crossref?
We designed the Crossref Metadata Sprint as a relatively short event where people can form teams and tackle short problems. What kind of problems? While we expected many to involve coding, teams also explored documenting, translating, researching—anything that taps into our open, member-curated metadata. Our motivation behind this format was to create a space for networking, collaboration, and feedback, centered on co-creation using the scholarly metadata from our REST API, the Public Data File, and other sources.
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.
Members can participate in Cited-by by completing the following steps:
Deposit references for one or more prefixes as part of your content registration process. Use your Participation Report to see your progress with depositing references. This step is not mandatory, but highly recommended to ensure that your citation counts are complete.
We will match the metadata in the references to DOIs to establish Cited-by links in the database. As new content is registered, we automatically update the citations and, for those members with Cited-by alerts enabled, we notify you of the new links.
Display the links on your website. We recommend displaying citations you retrieve on DOI landing pages, for example:
If you are a member through a Sponsor, you may have access to Cited-by through your sponsor – please contact them for more details. OJS users can use the Cited-by plugin.
Citation matching
Members sometimes submit references without including a DOI tag for the cited work. When this happens, we look for a match based on the metadata provided. If we find one, the reference metadata is updated with the DOI and we add the "doi-asserted-by": "crossref" tag. If we don’t find a match immediately, we will try again at a later date.
There are some references for which we won’t find matches, for example where a DOI has been registered with an agency other than Crossref (such as DataCite) or if the reference refers to an object without a DOI, including conferences, manuals, blog posts, and some journals’ articles.
To perform matching, we first check if a DOI tag is included in the reference metadata. If so, we assume it is correct and link the corresponding work. If there isn’t a DOI tag, we perform a search using the metadata supplied and select candidate results by thresholding. The best match is found through a further validation process. Learn more about how we match references. The same process is used for the results shown on our Simple Text Query tool.
All citations to a work are returned in the corresponding Cited-by query.
