With the increasing ranks of cell phone ownership is an increase in text messaging, or texting. During 2008, more than 2.5 trillion text messages were sent worldwide--that's an average of more than 400 messages for every person on the planet. Although many of the messages teenagers text each day are perhaps nothing more than "how r u?" or "c u l8r," texting plays an increasingly prominent role in the everyday lives of young people, and that role is not without controversy. This article examines some of those controversies--linguistic and behavioral--and describes how texting plays a greater role in librarians' work with young people in schools and school libraries. For the purposes of this article, texting serves as an umbrella term encompassing several discrete concepts and activities: text messaging, short message service, and Twitter.
