Two respected publishers now offer e-discovery (EDD) help, both supported by advertising. 

Law.com (ALM) offers its e-discovery roadmap and Findlaw (Thomson) its Electronic Discovery Rule Wizard. The former is organized by stage of EDD processing, the latter by the FRCP. Both have interesting interfaces, offer some substantive content, and link to advertisers.

I recently wrote about how technology may change traditional legal publishing. Neither of these appear to offer sufficient depth to threaten traditional research, but they may reflect yet another new legal publishing model.
