They’ve been busy. Google have released 2 further applications this week. The first is Google video. THois has been coming for a while, as they have been requesting video submissions. Now they release a search method for them. Each video appears to have documented metadata and transcripts (as far as possible) which are searchable. To watch the videos you need to download a plug in (which has already been hacked).
On a more ‘traditional’ route, Google Print is also in beta. Google print searches the text of books that have been provided from publishers and libraries. In many cases, the search results link to online publishers/sellers. so you can purchase there and then.
