I wasn't able to edit the "official" google doc or zoho doc. But I have used google docs for classwor, to collaborate on papers, class assignments and other goodies. Since I had a google account I just used that, and here's a link a of document we edited for class: this was for begining cataloging. What did we think were appropriate subject headings for the sample books? Our version of tagging...we all overlapped a bit. Maybe with a sample of millions, we's hit the mark.
