It looks like it's trying to be a better datasheetarchive.com, which is definitely nice to have because those sites are utter crap. However, I guess these guys will have to play catch up getting google to index all their datasheets, so when I google "lm1117t", I actually get the relevant power regulator datasheet.

At the moment, they appear to be relatively empty. I tried searching for anything beginning with "LM" or "2N" and got basically nothing. Would be nice to have a few of the basic components in there!
