Some fab new additions to Google Book Search:

   * A drop-down menu to navigate directly to a chapter.

   * A YouTube-like “embed this book” code snippet.

   * Sort search results by “relevance”, as well as page order.

   * Expanded Book Overview page, with reviews and more keywords.

There are a few more additions, only applying to public-domain books.

Interestingly the new contents listing doesn’t seem to wholly rely on a table-of-contents, since Google apparently has a new “structure extraction technology” which is being added to the mix.
