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.
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.
In 2013 Crossref embarked on a project to better support Crossref members and researchers with Text and Data Mining requests and access. There were two main parts to the project:
To collect and make available full-text links and publisher TDM license links in the metadata.
To provide a service (TDM click-through service) for Crossref members to post their additional TDM terms and conditions and for researchers to access, review and accept these terms.
To date, 37.5 million works registered with Crossref have both full-text links and TDM license information. We continue to encourage all members to include full-text links and license information in the metadata they register to assist researchers with TDM. You can see how each member is doing via its Participation Report (e.g. Wiley’s).
Members are also making subscription content available for text mining (temporarily or otherwise) for specific purposes, such as to help the research community with its response to COVID-19. Back in April we highlighted how this can be achieved by including:
A “free to read” element in the access indicators section of publisher metadata indicating that the content is being made available free-of-charge (gratis)
An assertion element indicating that the content being made available is available free-of-charge.
To access Crossref’s click-through tool for text and data mining, users could log in via their ORCID iD. They could then review TDM license agreements posted by Crossref members and accept, reject or postpone their decisions until later. Having agreed to a publisher’s terms and conditions this action was logged against the user’s API token which they could use when requesting full-text from the publisher.
Since the pilot in 2014, only 2 publishers have continued with the tool and fewer than 300 API tokens have been issued.
Publishers have since developed their own mechanisms for managing TDM requests. The introduction of UK (2014) / EU (2019) copyright exceptions for TDM has significantly reduced the number of requests and at the same time, more and more content is published under an open access license.
Given the low take-up of the click-through by both publishers and researchers, its goals are no longer being met. Therefore we will retire the TDM click-through in December 2020. Until that date, it will still operate for the two publishers and various researchers who use it while they finish implementing their alternative plans.
Crossref will continue to collect member-supplied TDM licensing information in metadata for individual works, and researchers can continue to find this via the Crossref APIs.
