LexisNexis and Westlaw
Generally, there is not a lot of information on human rights available on these research platforms. Lexis and Westlaw do provide access to newspapers, journal articles, and some treaties and agreements. Lexis provides access to the European Human Rights Reports from 1960 on, and Westlaw provides access to ICJ, ICTY, and ICTR cases.
