It was announced on Twitter by Google’s Satyajeet Salgar that the company has launched the “book preview” feature on mobile search results that has been seen on Google desktop search. This means that if you’re in a region where book previews are allowed, and a book has previews available within Google Book search, Google will show you the “preview book” link.
Satyajeet took this screenshot:
I was able to replicate it myself:
“You can now preview books on Google on mobile,” Satyajeet added.
By clicking the link, you’ll be taken into a nice mobile view of the book preview interface in Google Book Search.
