Dec 31, 2021 - On to 2020 two


About this time last year we were wrapping up 2020 and thinking maybe we’d be heading to a bright new post-COVID future… oh how naive we were! So here we are at the at the end of 2021 and the future at time remains uncertain from a global health perspective. Over the last year, we’ve seen some engineering researchers publishing on COVID-19 on issues related to detection, masks, filtration, etc.

We’ve ended the year with a grand total of 2061 preprints hosted on Engineering Archive, which includes 614 new preprints over the past year. This is down slightly from 2020 but we’re OK with that. The pandemic has taken a toll on all of us and even engineering researchers/scholars deserve a break.

engrXiv cummulative preprint count

Preprint downloads have doubled in the last year from 620,000 at the end of 2020 to 1,221,897 cummulative downloads to date! This brings a lot of value to the engineering research community.

The maintenance and development of Engineering Archive continues to be supported through Open Engineering, a 501(c)(3) nonprofit organization for the promotion of open practices in engineering in all forms. Donations are welcome!

We continue to appreciate the support of the Engineering Archive Membership Circle. The Membership Circle creates the opportunity for institutions, libraries, and other organizations to support the sustainability of the server through a $500 annual contribution. We are especially grateful to those organizations who have newly joined in 2021, West Virginia University Libraries and TU Delft Open Publishing! Of course this doesn’t make us appreciate our sustaining members any less, some of which have been supporting Engineering Archive for three years!

Interested individuals can reach out to to learn more or to request to join the Membership Circle.

HAPPY NEW YEAR to all Engineering Archive researchers, readers, institutional supporters, donors, and other users. We have some big things coming in 2022, some of which we will be able to announce shortly so stay tuned!

Nov 21, 2021 - 2000 eprints


This past week, Engineering Archive surpassed 2000 hosted eprints on the server. While the first 1000 preprints milestone took approximately 4 years to achieve, the second 1000 took only 18 months!

Once again, thank you to the engineering community for supporting Engineering Archive and we look forward to your continued support in the future!

Oct 18, 2021 - 1000000 downloads


According to our stats, engrXiv has surpassed 1,000,000 downloads of the content we host! This represents a significant savings to the engineering research community. If each of those downloads represented a purchase of a paywalled article, that would be around $25,000,000 saved.
