Open Source Electronic Lab Notebook is an open-source, digital lab notebook.
With OS-ELN, you can sign up for a notebook and quickly begin recording your experiments. You can easily attach files to experiments, and keep all your data organized in one place. If you're familiar with Zope, you can even customize the system to suit your needs. This might include changing the look and feel, accessing relational databases, or adding other content to experiments.
However, there are some limitations to OS-ELN. If you're doing work that may lead to a patent claim or might be regulated by organizations like the FDA, you should probably avoid using OS-ELN. It's best suited for simple, non-confidential experiments. If you need a more robust ELN, it will be worth investing in a commercial product or relying on paper documentation instead.
