[Air-L] Sources on text messages

A graduate student I'm working with is interested in writing about text messaging in close relationships with family, partners, and friends, and particularly in the ways typical patterns of conversation are translated into and modified in the move from telephone to text message. Any ideas for sources to help get her started would be appreciated. Thanks, Linda -- Linda Levitt, PhD Assistant Professor, Communication Studies Stephen F.
