Frankfurt Book Fair (#FBM20) will be online this year since people are really not traveling right now. This special edition of #FBM20 will have an extensive digital program in which we will be participating. So you can hang out with us from anywhere in the world!
If you manage a publishing system or workflow, you know how crucial—and how challenging!—it is to have clean, consistent, and comprehensive affiliation metadata. Author affiliations, and the ability to link them to publications and other scholarly outputs, are vital for numerous stakeholders across the research landscape. Institutions need to monitor and measure their research output by the articles their researchers have published. Funders need to be able to discover and track the research and researchers they have supported.
Many researchers want to carry out analysis and extraction of information from large sets of data, such as journal articles and other scholarly content. Methods such as screen-scraping are error-prone, place too much strain on content sites and may be unrepeatable or break if site layouts change. Providing researchers with automated access to the full-text content via DOIs and Crossref metadata reduces these problems, allowing for easy deduplication and reproducibility. Supporting text and data mining echoes our mission to make research outputs easy to find, cite, link, assess, and reuse.
Crossref’s Similarity Check service is used by our members to detect text overlap with previously published work that may indicate plagiarism of scholarly or professional works. Manuscripts can be checked against millions of publications from other participating Crossref members and general web content using the iThenticate text comparison software from Turnitin.
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.
