The article The Many Faces of E-Lawyering in the Jan/Feb issue of Law Practice provides a good survey of many online legal services topics.
The article, edited by Richard Granat and Marc Lauritsen, the Co-Chairs of the ABA eLawyering Task Force, is a compendium of several shorter pieces: online services for consumers, e-learning tools, document assembly on extranets, managing cases online, browser-based advice systems, and legal cybernautics (you’ll have to click through to read this thought provoking item).
This is a good spectrum of topics and views, though I’m not disinterested since I contributed the browser-based advice systems section.
