In 2020 we released our first public data file, something we’ve turned into an annual affair supporting our commitment to the Principles of Open Scholarly Infrastructure (POSI). We’ve just posted the 2022 file, which can now be downloaded via torrent like in years past.
We aim to publish these in the first quarter of each year, though as you may notice, we’re a little behind our intended schedule. The reason for this delay was that we wanted to make critical new metadata fields available, including resource URLs and titles with markup.
Unfortunately, Bryan Vickery has moved onto pastures new. I would like to thank him for his many contributions at Crossref and we all wish him well.
I’m now pleased to announce that Rachael Lammey will be Crossref’s new Director of Product starting on Monday, May 16th.
Rachael’s skills and experience are perfectly suited for this role. She has been at Crossref since 2012 and has deep knowledge and experience of all things Crossref: our mission; our members; our culture; and our services.
Since we announced last September the launch of a new version of iThenticate, a number of you have upgraded and become familiar with iThenticate v2 and its new and improved features which include:
A faster, more user-friendly and responsive interface A preprint exclusion filter, giving users the ability to identify content on preprint servers more easily A new “red flag” feature that signals the detection of hidden text such as text/quotation marks in white font, or suspicious character replacement A private repository available for browser users, allowing them to compare against their previous submissions to identify duplicate submissions within your organisation A content portal, helping users check how much of their own published content has been successfully indexed, self-diagnose and fix the content that has failed to be indexed in iThenticate.
A re-cap We kicked off our Ambassador Program in 2018 after consultation with our members, who told us they wanted greater support and representation in their local regions, time zones, and languages.
We also recognized that our membership has grown and changed dramatically over recent years and that it is likely to continue to do so. We now have over 16,000 members across 140 countries. As we work to understand what’s to come and ensure that we are meeting the needs of such an expansive community, having trusted local contacts we can work closely with is key to ensuring we are more proactive in engaging with new audiences and supporting existing members.
Cited-by gives our members full access to citations, helping them to build a picture of how research has been received by the community.
Scholars use citations to critique and build on existing research, acknowledging the contributions of others. Members can include references in their metadata deposits which Crossref uses to create links between works that cite each other. The number of citations each work receives is visible to anyone through our public APIs. Through our Cited-by service, members who deposit references for their content can retrieve and display itemized lists of works that cite their own.
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:
Cited-by begins with depositing references as part of the metadata records for your content. Learn more about depositing references.
A member registers content for a work, the citing paper. This metadata deposit includes the references list. Crossref automatically checks these references for matches to other registered content. If this is successful, a citation is created.
Crossref logs the citations and updates the citation counts for each work. You can retrieve citation counts through our public APIs. Members who deposit references can sign up for the Cited-by service to retrieve the full list of citing works (not just the count), and can display them on their website. Cited-by complements citation counts by allowing access to the detail of each citation, even in cases where members have have chosen to set their references to <em>limited</em> or <em>closed</em>.
Note that citations from Crossref may differ from those provided by other services because we only look for links between Crossref-registered works and use a different matching algorithm.
Obligations and fees for Cited-by
Participation in Cited-by is optional, but encouraged
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.
Best practice for Cited-by
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.
Also in the metadata is the number of citations a work has received, under the tag "is-referenced-by-count".
However, to retrieve the full list of citations for your own works, you need to register for Cited-by. While anyone can use an API query to see the number of citations a work has received, through Cited-by the member who deposited the work can retrieve a list of citing DOIs. Details of the citing works can be displayed on your website alongside the article.
In addition, Cited-by users can receive callback notifications or emails informing them when one of their works has been cited.
