OS-ELN is an Electronic Lab Notebook which you can freely download and use.

OS-ELN is deliberately simple; fully-fledged commercial ELN's are necessarily much more complex. As such, OS-ELN is a good teaching tool and a place for experimentation with ELN technology and concepts.

Users can sign up for an ELN, within which they can record their experiments, and you can attach files as part of an experiment. With knowledge of Zope, you can expand the system as you wish, for example to change the look & feel, to access relational databases, add other content to experiments, etc.

Limitations:

· You would be very unwise to use OS-ELN to document work that may lead to a patent claim (or defend against a patent infringement action) or for work that may be regulated (by, for example, the FDA). You should either buy a commerical ELN or use paper.
