Transforming the Law by Richard Susskind, published by Oxford University Press (ISBN 0198299222)

First point. Richard Susskind is the nearest thing the law has to an e-guru.

As a speaker at almost any conference on technology and the law, and as IT adviser to the Lord Chief Justice, his face and his Powerpoints are well known.
Second point. Although there are many books on e-business, e-management and e-verything else, there are very few on the law or the business of the law. You can read between the lines of many good texts but you will be hard-pressed to find one with case studies from law firms.
Two good reasons to go out and buy a copy of Transforming the Law. This collection of essays distils Susskind's thoughts on what is happening to the law and the business of the law as it grapples with networks. Admirably clear, user-friendly and comprehensive in its focus on law, these essays are the nearest thing we have to a primer. As such they should be required reading for anyone faced with the task of dragging a firm into the new reality or coming to terms with what law will be in the new world.
But the problem comes in that Susskind is a legal man. As such, his book remains almost too grounded, the transformations too controllable, the diagrams too simple.
No one can predict how the network effect will work itself out or how the redrawing of power relationships will settle, or if they ever will. If there is a lesson to be learnt for those managing this change, it is not to try and manage it. But that lesson does not make for neat presentations.
