2020 wasn’t all bad. In April of last year, we released our first public data file. Though Crossref metadata is always openly available––and our board recently cemented this by voting to adopt the Principles of Open Scholarly Infrastructure (POSI)––we’ve decided to release an updated file. This will provide a more efficient way to get such a large volume of records. The file (JSON records, 102.6GB) is now available, with thanks once again to Academic Torrents.
Our colleague and friend, Kirsty Meddings, passed away peacefully on 10th December at home with her family, after a sudden and aggressive cancer. She was a huge part of Crossref, our culture, and our lives for the last twelve years.
Kirsty Meddings is a name that almost everyone in scholarly publishing knows; she was part of a generation of Oxford women in publishing technology who have progressed through the industry, adapted to its changes, spotted new opportunities, and supported each other throughout.
Crossref has supported depositing metadata for preprints since 2016 and peer reviews since 2018. Now we are putting the two together, in fact we will permit peer reviews to be registered for any content type.
2020 has been a very challenging year, and we can all agree that everyone needs a break. Crossref will be providing very limited technical and membership support from 21st December to 3rd January to allow our staff to rest and recharge. We’ll be back on January 4th raring to answer your questions. Amanda explains more about why we made this decision.
Cited-by shows how work has been received by the wider community; displaying the number of times it has been cited, and linking to the citing content.
Researchers cite other people’s work to acknowledge the material they used when writing their own paper. It’s useful to see which articles go on to cite the paper you’re reading, and how it may have built on or challenged its ideas.
Cited-by allows Crossref members to find out who is citing their content. Members can then display the counts and link to the citing content on their own work. Cited-by counts are publicly available, but only the member can see the details of which sources are citing their works.
Members who use this service are helping readers to:
easily navigate to related research,
see how the work has been received by the wider community, and
explore how ideas evolve over time by highlighting connections between works.
Watch the introductory Cited-by animation in your language:
Crossref members tell Crossref what content their papers are referencing by including that information as metadata when they register content. Users of the Cited-by service can then query that metadata to see which sources are citing their content.
To participate in Cited-by, you need to be a member, and you need to include references in your own metadata. Once you’re enabled for Cited-by, you you’ll able to query publications that cite your content. This allows for the display of citation counts and lists on articles so readers can see that the content they’re reading is being cited, as in this Australian Journal of Linguistics example:
Cited-by counts complement rather than replace other services, and may differ from those of other citation databases, such as Google Scholar, Scopus, and Web of Science, which use a variety of sources for their citation data. Crossref Cited-by counts are based on the citation counts of other Crossref members participating in Cited-by.
Obligations and fees for Cited-by
Participation in Cited-by is optional
There is no charge for Cited-by
You must include references when you register content, in order to be eligible for Cited-by
You only retrieve Cited-by metadata for your own content
Our public APIs include Cited-by counts but not the actual works.
We match the metadata in the references to DOIs to establish a Cited-by relationship in the database. As new content is registered, we automatically update the relationships and notify you of new links.
Participation in Cited-by is optional, but encouraged
Because citations can happen at any time, Cited-by links must be kept up-to-date. Members should either check regularly for new citations or (if performing XML queries) set the alert attribute to true. This means the search will be saved in the system and you’ll get an alert when there is a new match
Once retrieved, Cited-by counts should be included and linked on your website.
The Crossref system establishes a Cited-by relationship between articles X and Y
Member A later sends a query asking who cites article X and is given the DOI for article Y and its metadata.
Currently only the member who owns an item may ask for the Cited-by data about that item. So in the example above, member C could not inquire about the Cited-by relationship of articles X or Y. The order of events may vary from what is shown in this simple example, for example, step 2 could occur before step 1. The Crossref system is set up to handle this by ‘remembering’ the citation in article Y and will establish the relationship whenever article X is ultimately deposited.
