NotedELN is an open-source electronic laboratory notebook (ELN) "with a focus on getting things done."[2]

Product history

Developer and research scientist Daniel Wagenaar started the eln project on Launchpad on June 14, 2013 and deposited a version 0.1.1 onto the site the same day.[2][1] It's assumed work began on the software before then, as Wagenaar refers to the software as "fairly mature and used daily in our lab" on his lab's web page.[3]

In July 2021, the project was renamed from "eln" to "NotedELN" "to avoid confusion with other electronic lab notebooks."[4]
