If you're not big into snapping selfies maybe you'll like the new trend of taking "shelfies." It means just what it sounds like, people are snapping photos of their book shelves and posting the photos on social media with the hastag #shelfie. Those who aren't readers are choosing to photograph other artfully-arranged shelving units in their kitchen, bedroom, or other rooms instead. Even bookstores and publishing houses are getting in on the "shelfie" trend. The Wall Street Journal defines "shelfie" as "a photo of one's possessions arrayed on a surface, such as a shelf."
