I'm a developer at enigma.io, which is a public data search-and-discovery platform. With following all of the PRISM stories, I've been looking into the data we have on U.S. government contacts going back until 2006 and found a lot of interesting entries where Google is the vendor (descriptions for the servies include supoenas for personal data, "information check", "expediting records", "subscriber info", etc)...
I collected exports of these datasets filtered to where Google is the vendor and threw it up on Google Drive (lol) over here:

You can also download a ZIP of all of the CSV's here:
