Anyone remember a site that recently was mentioned here with elearning ebooks?

There was a site mentioned here in the last month that was something of a site like wikibooks. I remember it was mentioned as having especially good resources on electrical engineering. Anyone have any ideas what this site might be?

Thanks.
