Probono.net is a national, online resource for legal aid and pro bono attorneys, law professors and students, and related social services advocates. The site promotes collaboration and makes it easier for pro bono attorneys to get involved, saving them time and connecting them with opportunities, training events, mentors, and searchable libraries of practice resources they won't find anywhere else. The site is organized by topical "practice areas" and geographic regions, built and maintained by public interest legal organizations and law firms throughout the country. Members include more than 45,000 advocates from hundreds of public interest organizations and private firms. Probono.net works in close partnership with nonprofit legal organizations across the United States and Canada, to increase access to justice for the millions of poor people who face legal problems every year without help from a lawyer.

Pro Bono Net is a national nonprofit organization based in New York City and San Francisco. Founded in 1998 with a grant from the Open Society Institute, Pro Bono Net has developed a broad base of support from foundations, law firms, corporate sponsors and nonprofit partners alike, to build web platforms that offer powerful and sophisticated online tools to pro bono and legal aid advocates, and to provide critical legal information and assistance directly to the public.
