Since 1978, when we published our first list of 200 firms, and 1983, when we expanded the list to 250, The National Law Journal‘s annual law firm survey has identified the largest legal players in the United States — ranking them by headcount and providing detail about their locations, partners, associates and other attorneys.

This year, we launched our biggest-ever expansion of the survey, adding 100 additional firms to our list, ranked from No. 251 to No. 350. The new list provides a closer look at the growing midsize law firm market and includes a number of regional players outside the big cities that dominate our traditional NLJ 250 survey.
