Please excuse cross posting.

The NDSA Fixity Working Group is back with our third iteration of the NDSA Fixity survey. Please contribute to our longitudinal research designed to gain insight into how organizations worldwide use various fixity methods to ensure the stability of their digital content and to learn how real-world capacity and best practices differ.

The survey is open now and will be available until September 15, 2025. The survey is expected to take approximately 25-30 minutes to complete. You are able to come back to a partially completed survey if you use the same computer and browser. To assist with completing the survey, all of the survey questions can be viewed in advance by following the link to this Google PDF.

Interested in the results of our previous surveys done in 2017 and 2021? Please check out the code book, data, and report on the 2017 Fixity Survey OSF page and 2021 Fixity Survey OSF page.

If you have questions or concerns about this survey, please contact the NDSA Fixity Working Group at NDSA-FIXITY@lists.clir.org.

Thank you for helping NDSA and our community define and advance digital preservation!
