My Other Bookmark Is a Pen

Google sent me a set of bookmarks, perhaps as a thank-you for buying an ebook from them. The bookmarks, one each in the four standard Google colors, say:

  • My other book is a smartphone.
  • Take your library anywhere.
  • My other book is a tablet.
  • My other book is a laptop.

According to Google, my library consists of one printed book, and one device that is a combination smartphone, tablet, and laptop.

Which leads me to the question, since you have only one book, what will you do with the other three bookmarks?
