When Worlds Collide

As you walk into the library, the hushed tones enveloping you, you walk to the books, and browse your way along the isles. You trail your hand along the endless books, their leather spines soft under your touch, and you wait for one of them to call out to you. A book catches your, eye, and you read the title and blurb satisfied with your choice. You quickly bring it to one of the many cozy chairs, settle in, and begin to read the novel.
What do the others see?
