Most online library catalogs have a browse function that lets you see which books are shelved together. A killer app for VR would be to browse Amazon's bookstore virtually. Imagine walking through the shelves of the biggest library in the world, pulling out a book, and reading it (even if it's just a snippet). Add multiplayer capabilities so you can interact with other library patrons and you've got perhaps the most addictive "game" ever created. This could be extended to create virtual product libraries. I would be really surprised if someone isn't working on this yet.
