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.
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:
Click Last Crawl Date to view a crawler status report for a title:
The crawler status report lists the following:
Total DOIs: Total number of DOI names for the title in system on last crawl date
Checked: number of DOIs crawled
Confirmed: crawler found both DOI and article title on landing page
Semi-confirmed: crawler found either the DOI or the article title on the landing page
Not Confirmed: crawler did not find DOI nor article title on landing page
Bad: page contains known phrases indicating article is not available (for example, article not found, no longer available)
Login Page: crawler is prompted to log in, no article title or DOI
Exception: indicates error in crawler code
httpCode: resolution attempt results in error (such as 400, 403, 404, 500)
httpFailure: http server connection failed
