Frequently Asked Questions


When will the migration take effect (the new site launches and the old site goes down)?

The migration is scheduled for February 17, 2021. We will confirm the date and time when we are closer to launch.

Where can I access the new content site? Will the base URL be changing?

Project Euclid will continue to be hosted at However, article level URLs will change. See the URL crosswalk file.

What can I do on the beta site?

The beta site will remain available through February 15 to allow librarians additional time to test all functionality. Please visit the migration checklist for items that you may wish to test on the beta site prior to launch, as well as on the live site after launch. Please note that Shibboleth authentication will not be available on the beta site, but will authenticate on the live site at launch.

What content is affected by the platform change?

All content hosted on will be affected. KBART title lists are available on KBART title lists page.

What do I do if my library loses access during the transition?

Please contact Sending questions to this address allows us to efficiently track and provide answers to your questions, making sure we direct your questions appropriately. 

Will my institution have access to both platforms simultaneously?

No. The existing content URLs will redirect to the new platform at launch. This redirect process takes a short period of time to complete. The current site will be down February 16 and no content will be available until the new platform is live on February 17.

Will the URLs change? When will they be available?

Yes, the URLs for all publications will change. All URLs on the retired platform will redirect to the new platform. The current "Title Crosswalk" includes new journal-level URLs and will be updated with book and proceedings-level URLs when that information has been finalized. We are also working with library service and discovery vendors to ask that the URLs in their knowledge-bases be updated for launch.

Will I be able to test the new site prior to launch?

Yes, librarian account administrators were invited to begin testing a preview version of the site in November 2020. If you need access to the test site and have not received the URL, please contact

Will my platform administrator username and password change? 

Yes. We have been contacting library account administrators with instructions on how to sign in and update your account. See the password reset instructions.

I have multiple administrative accounts on Project Euclid. Will this change on the new platform?

Yes. There will be one user account for all of your institutional holdings on Project Euclid. The new platform will not allow multiple accounts to hold overlapping IP addresses. We will provide more information on administration accounts as it becomes available.

What features will be available through my library administration account on the new platform?

You will be able to update your contact information and IP addresses; pull usage statistics; review access and entitlements; monitor abuse logs; and control the institutional branding displayed to your patrons.

Will all of the book and journal content be available on the new platform when it launches?

Yes, 100% of our content will be available on the new platform at launch. We are not migrating in stages. All holdings may not be comepletely represented immediately in the test site; this is a known issue.

Will my usage statistics for Project Euclid content hosted on the retiring platform be available on the new platform?

COUNTER 5 reports starting with January 2019 data will be loaded into the new library administration tools. Older usage from the current platform and COUNTER 4 reports will not migrate to the new platform. You will need to pull all of your institution’s historical usage statistics from Project Euclid before the new site launches. We will provide deadlines for downloading historical usage at a later date.

How do I set up a SUSHI feed to gather my usage reports on the new platform?

SUSHI will be available on the new platform, but not on launch date. We will be in touch once COUNTER reports are available on the new platform, with instructions on how to gather those reports. We expect COUNTER reports and SUSHI to be available within a few weeks of launch.

Will there be new EZ Proxy stanzas?

No, EZ Proxy stanzas will not change.

Do we need to set up a new admin account? 

Yes, you can find instructions here.

Are you working with Library Management System providers? 

Yes, we are communicating with all of the major discovery vendors, including ExLibris, EBSCO and OCLC.

Will the redirects be for DOIs only? Will the redirects be permanent or temporary? 

The redirects are not for only the DOIs and will be permanent.

What will happen on launch day? What should I expect?
The migration process will begin at 11 am EST on Wednesday, February 17. The majority of users will see an immediate switch, but different internet service providers and browsers may clear their caches and propagate the change at different rates. We expect all users to see the new version of the site by noon EST on Thursday, February 18.

What happens if the migration timeline is delayed?

The information we have provided is up to date. If the timeline changes, we will update Project Euclid Platform Migration page and be in contact with account administrators.

What do I need to do right now?

  1. Invite all affected colleagues to sign up for our mailing list
  2. Keep an eye out for future announcements.
