use modified versions of Open source software. Most law firms also subscribe to a Computer-assisted legal research database for Legal research. Such databases provide Case law from case reporters, and often other legal resources. The two largest legal databases are Westlaw (part of West, which is owned by Thomson Reuters) and LexisNexis, but other databases also exist, including the free Google Scholar, and the newer Bloomberg Law, as well as Loislaw (operated by Wolters Kluwer) and several smaller databases. Some bar associations and lawyers' organizations have their own software.
