Here's a quick look at the big G's new domain names:
Source: SearchEngineWatchGoogleMagazines.com
also registered in the .net, .org, and .info domains.
GooglePapers.org
also registered in .net and .info domains. GooglePapers.com is registered to a person in British Columbia.
GoogleMicrofilm.com
also registered in the .net, .org, and .info domains. Forget books. We do know that LOTS of microfilm needs to be digitized. (-: Other than that, speculate all you want, or not.
GoogleLibrary.org
GoogleLibrary.com, .net, and .info are registered to others. Here's a chance to get at least one domain.
