[Air-L] Literature on digital comm professionals?

Can anyone recommend a few must-read articles/books on digital communication professionals? I'm thinking about people like social media managers, copywriters, PR/outreach/communication strategists, designers, etc. Even more software development-oriented professions would be useful. Thanks (and apologies if you already saw this on the FB group). - - - - - Luis E.
