The article this links to is interesting enough, but what's really interesting is some of the discussion about how people do, or think people should, approach keeping electronic lab notebooks.

I feel you can tell which are the comments from software developers who don't really appreciate the requirements; they are, understandably, the ones who focus on change histories and the like, without picking up on the fact that generally you don't ever want people going back and changing anything.

As someone who works with people who need to deal with this, it's an interesting read and follows a lot of my journey from ignorance on the subject to some appreciation of the issues.
