Hit hard in recent years by the rise of Google, the evolution of law firm Web sites and the emergence of competing Internet-based legal directories and ratings services, 140-year-old Martindale-Hubbell is giving itself a technological face-lift in a bid to remain vital.

In mid-July, the company, a unit of the LexisNexis Group of London-based publishing giant Reed Elsevier, announced that it had entered a partnership with Mountain View, Calif.-based LinkedIn, a career-focused social network. The move follows decisions earlier this year to incorporate video clips and “visibility ratings” into Martindale’s beefed-up lawyer profiles.
