eln 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]


Features of eln include[2][3]:

  • data import
  • internal and external linking
  • entries and images stored in hierarchical folder structure
  • automatic table of contents generation
  • autosave feature
  • drag-and-drop and cut-and-paste support
  • automatically saves PubMed docs

Hardware/software requirements
