It's the end of another eventful week in search blogging, and once again there are several Google updates just piled up waiting to be written about. So, we're saving everyone some time and just compiling them into one post. Check them out:

Google News has a new sitemaps interface. You have six months to adopt the new sitemap.

Google Books now has a magazine search page.

Via Google Search's new music search, you can now access exclusive songs hosted by MySpace and Lala for artists such as Lady Gaga and Arctic Monkeys.

Google Maps has released imagery of Berlin from 1945 to 1953.

The Google Mobile App is now available at Best Buy (still free, which is the ultimate "best buy").
