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.
It’s me! Back in January I wrote, The one constant in Crossref’s 20 years has been change. This continues to be true, and the latest change is that I’m happy to say that I will be staying on as Executive Director of Crossref. At the recent Crossref board meeting, I rescinded my resignation and the board happily accepted this.
Please help us welcome new faces at Crossref! Martyn, Sara, Laura, and Mark joined us very recently and we are happy they’re with us. Both Martyn and Sara have joined the Product team and this has given us the chance to reorganize the team into the following groups: content registration, scholarly stewardship, scholarly impact, metadata retrieval, and UX/UI leadership. Laura joined the Finance and Operations team to help make the billing process simple for our members. Mark joins the Technology team and one of his projects will be improving the Event Data service.
It is exciting to already see the impact of your contributions and look forward to what’s to come!
2020 hasn’t been quite what any of us had imagined. The pandemic has meant big adjustments in terms of working; challenges for parents balancing childcare and professional lives; anxieties and tensions we never had before; the strain of potentially being away from co-workers, friends, and family for a prolonged period of time. Many have suffered job losses and around the world, many have sadly lost their lives to the virus.
We test a broad sample of DOIs to ensure resolution. For each journal crawled, a sample of DOIs that equals 5% of the total DOIs for the journal up to a maximum of 50 DOIs is selected. The selected DOIs span prefixes and issues.
The results are recorded in crawler reports, which you can access from the depositor report expanded view. If a title has been crawled, the last crawl date is shown in the appropriate column. Crawled DOIs that generate errors will appear as a bold link:
