Four years ago, Richard Susskind published the first edition of “Tomorrow's Lawyers: An Introduction to Your Future.” With the rapid changes in the legal profession, tomorrow is now today.

The second edition of “Tomorrow's Lawyers,” widely considered a must-read for business of law and legal education professionals, focuses more sharply on how artificial intelligence, alternative business structures, low-cost law firm service centers, legal tech startups and evolving in-house roles are changing the way legal services are delivered and how law schools are educating students to meet those changes.

You'll recall from Susskind's first edition his credibility as a futurist: He's devoted his career to theorizing about and planning for the legal profession's long term. (You might also remember he predicted in the first edition a relentless march by the Big Four accounting firms into the legal services market, a prediction proven accurate last month when we broke the story that PricewaterhouseCoopers is launching a D.C. legal services office.)
