More Library Links in Google Book Search

The Google Blog, in a post entitled "Find the wealth in your library" talks about the expansion of links to national library union catalogs at Google Books. More than 15 union catalogs are includes, not just Open WorldCat. It is not always easy to connect to each of these union catalogs, and I still find plenty of records without a "Find this book in a library" link, even when the books are listed in WorldCat. Gary makes some pointed comments as well.
