ChemRxiv Site Migration FAQs


In January 2026, ChemRxiv will be moving to a brand new hosting platform, Wiley's Research Exchange Preprints. The site will still available at chemrxiv.org. We are excited about all the great benefits that this new platform will bring, but we want to acknowledge that there will be a short interruption in handling new submissions while we finish moving our backfile of preprints (36,000+ and growing!). The website will remain accessible for site visitors throughout the transition, meaning no interruption in reading and discovering our preprints.

Please read further for more details. If your question isn’t answered here, please contact us at support@chemrxiv.org at any time. We are grateful for your support and patience as we bring ChemRxiv into its next phase of growth.

You can also follow us on Twitter @ChemRxiv, on BlueSky at @chemrxiv.org, or sign up for our email list so you don’t miss anything.

Timeline


What is the timeline for the transition?

We are currently targeting a launch date for the new platform of January 21, 2026. We will update this page if any change to this timeline is required.  

In order to move final content and data to our new platform, we will need to halt submission of new preprints and versions on January 14, 2026. This will allow our team to complete processing all recently submitted preprints and transfer them to the new database. If you have received a revision request from our staff, please address it and resubmit before January 14. Unreturned revisions will not be transferred to the new system.

Please note that the old site may still be visible to you when you visit chemrxiv.org for up to two days after launch of the new site due to web server caching. We will endeavor to minimize this effect as much as possible.

Site Function


Will my existing account and credentials still work?

Yes, you can log in with your ORCID on the new platform. If you previously submitted preprints that were published on ChemRxiv, those preprints will be found under ‘My Documents’ in your author profile. Previously declined submissions, incomplete submissions (‘in progress’), and unreturned revisions (‘revision requested’) will not be available on the new platform. 

For authors creating a new account, other authentication options will now be available.


Will previously published preprints remain accessible? What about old links and DOIs?

All published preprints will be accessible on the new platform. We are establishing web redirects so anyone with an old URL bookmarked can still find the same content.

We are also redepositing posting details with Crossref, meaning that prior DOIs will still resolve without being changed. They will lead to the new preprint article pages directly.

Submission Process


How will the new submission process differ from the old one?

You will find that very similar information is requested during submission. However, we are delighted to share that when you upload your PDF, our new system will extract basic bibliographic metadata (title, abstract, authors, affiliations) and present them to you for review. You will no longer have to enter details for each author during submission if they are present in the manuscript file.


What file formats are supported?

As with the current ChemRxiv site, we request that authors upload a PDF file for evaluation. The PDF file will be posted as is after our screening. Please do not use a journal/publisher template that includes a logo or copyright statement assigning rights to another party.

Curation and Site Policies


Will there be changes to the screening process?

No – we will still screen all incoming content exactly as we have done for years. A PhD chemist will ensure that the content is scholarly and fits our scope. We hope that the changes to streamline the submission process will enable faster screening as we move to the new platform.


Are there any changes to ChemRxiv policies or scope?

No. ChemRxiv will still post content that fits into one of our same 16 subject areas, and we will still accept full research manuscripts and review articles.

Site Features


Does the new platform support versioning?

Yes, you can upload a new version of a posted preprint by starting a new submission in your ‘My Documents’ list.


What other new features will the site include?

We are pleased to bring several new features that have been requested by our community. In addition to our automated metadata extractor:

  • The title and abstract are entered into the system using a feature-rich editor page, allowing for special characters and formatting. In fact, you could compose a full-text article with embedded figures and links in the editor if you choose!
  • If you are logged into ChemRxiv, you can now bookmark preprints from search results or the article page to add to a reading list.
  • Logged in users can also save searches for future use, or request daily, weekly, or monthly notification emails when new results to that search query are posted. 

Will any current features not be found on the new site?

There are a few existing features that will not be available immediately upon launch of the new platform. However, we are working to rebuild or replace these functions with something new after launch. The exact timing is still to be determined.

  • Direct Journal Transfer will not be available at launch. We are already in discussions with our new platform host to bring back this popular feature. We will be able to modernize the transfer process, allowing for further expansion of destination journals in the future
  • Commenting will not be available at launch. We have recently found that a large portion of our comments are spam, and we are investigating a good system to allow discussion about our preprints without being susceptible to inappropriate content.
  • The new platform will not support a dedicated ‘Revision’ status. However, when a preprint is declined, it is returned to your ‘Drafts’ queue. Therefore, you will not have to start a new submission from scratch to make any necessary changes before we can evaluate again.

Customer Support


Will there be information about how to use the new platform?

We are preparing a Submission Guide that will be launched on the new site to detail how to upload a preprint. We also will have a page of FAQs. Questions about the site are always welcome: support@chemrxiv.org.


How do I report technical issues or bugs?

If you come across any issues on the new platform, please contact us at support@chemrxiv.org. We will be monitoring closely after launch and addressing any issues as soon as possible. If you encounter an issue, providing us with a screenshot, the browser being used, and any other relevant details will be very helpful in assessing a potential fix.
