Enabling accurate results within the Journal Checker Tool

We’ve worked hard to ensure the results given within the Journal Checker Tool (JCT) are as accurate as possible at this point. However, not all of the data being used by the JCT is ours to update. The tool is a partnership between data sources, with data updates being made in the data sources themselves. The JCT helpdesk will help to coordinate data update requests, but for some changes, particularly at the portfolio level, updates need to be submitted directly to the original data source, including e.g. DOAJ or the ESAC registry. 

It’s in our collective interests to ensure that all the data used by the JCT is as fresh and complete as possible. We ask that publishers, consortia and institutions review their data within our sources such as DOAJ, our transformative agreement index and Shareyourpaper.org permissions to ensure that it reflects the current picture – something we know we don’t have right now for all journals. By taking action in the coming weeks, you are supporting researchers in enabling immediate access to research when Plan S launches on 1 January 2021. 

Fully open access journals

Our data source for fully open access (OA) journals is DOAJ. If a journal isn’t indexed in DOAJ it won’t appear within the JCT. That’s the first thing for publishers to check for their fully Open Access (OA) titles. DOAJ has its own editorial process for determining whether or not a journal can be indexed in it and this process takes time. Most applications are processed in under 3 months but it can take up to 6 months in some cases. Publishers should start to submit their applications to DOAJ now. DOAJ have recently published their Basic criteria and the application form is here: https://doaj.org/application/new. The JCT has access to data on titles that are in the process of applying to DOAJ. 

The JCT will use the metadata held within DOAJ about a journal to determine whether it enables researchers to comply with Plan S. For example, we will look at whether the licence recorded within DOAJ is CC BY or equivalent. If not, then the journal will be identified as not being compliant. Therefore a publisher should check whether the licence options recorded within DOAJ for their titles show the most permissive licence. DOAJ are shortly to launch a new website and application form, with an updated metadata schema. DOAJ has published instructions on how publishers can update their records

Journals under Transformative Agreements

We have built an index of Transformative Agreements (TAs) that have been registered within the ESAC Registry of Agreements. This index features information on the journals included within the agreement and the institutions that have subscribed to it. Agreements are listed within the index by their ESAC Registry Agreement ID, and the data can be downloaded from the JCT website for easy validation.

If you need to register your agreement in the ESAC Registry, you can do so here. Once uploaded to the registry it will be picked up as part of our TA data management process, which involves regular review cycles of agreements within ESAC and looking at the journals/institutions within each individual agreement. Consortia or publishers who wish to submit or update batches of data within the TA index should email jct[at]cottagelabs.zendesk.com


There are two routes to compliance through self-archiving within the JCT. The primary route is the journal’s own self-archiving policy, via the data source Shareyoupaper.org Permissions. Policies are monitored automatically and updated as required. However, if you would like to manually request an update you can do so here. If you’d like support and feedback while updating your policy, you can reach out to their team here.

If the data within Shareyourpaper.org Permissions does not reveal a policy that enables researcher compliance, then the JCT will look at whether the cOAlition S Rights Retention Strategy could be used as a route to compliance. Here the JCT will check if the funder of the research has implemented the Rights Retention Strategy. If so, Self-archiving via Rights Retention will be shown. For more information on Rights Retention see the related blog post: “4 things you should know about the Rights Retention Strategy and the Journal Checker Tool”. 

Transformative Journals

Transformative Journals are subscription journals that have committed to transitioning to fully open access according to the criteria set out by cOAlition S. A list of currently approved transformative journals are available from the cOAlition S website and in csv format from the JCT website. Subscription journals who wish to be considered as transformative journals by cOAlition S, and thus the JCT, should apply here. cOAlition S will process applications upon receipt, with data transferred to the JCT within a fortnight once an application has been approved.
