These contain the treaty text submitted by the executive branch to the Senate for “advice and consent” together with supporting documentation. For recent treaties, the Senate Treaty Document may be your only source for the treaty text . Pre-1979, these documents were called Senate Executive Documents.
Senate Executive Reports are issued by the Senate Foreign Relations Committee and contain the committee’s analysis and recommendations on a proposed treaty. These reports are in the Serial Set print and on the web since the 104th Congress.
Most US international agreements do not follow the traditional “advice and consent” route of going to the Senate for ratification. They are usually considered executive agreements and will not have the treaty documents above

Understand the structure of the foreign legal system – is it a civil law country or a common law system? Perhaps mixed?
What do you need – constitution, a statute, a citation. Full text or summary? In English?
What are the sources of law for the country? Does the country publish codes, statutes or reporters?
Consider reading a research guide on the topic or the country.
English language sources are usually the most sought after, but they must be used with caution. Most English translations are not official or authoritative, may not be up-to-date, and the quality may be an issue. Sometimes, you will have to rely on periodical literature for the text or summary. For some subject areas, such as taxation, commercial or business law, there are commercial compilations available. Court decisions and administrative law can be very difficult to locate in English. The following resource is a great starting point:
Foreign Law: Current Sources of Codes and Basic Legislation in Jurisdictions of the World , T. Reynolds & A. Flores [K38 .R49 1989 Intl Ref] Also available electronically under Research Databases (GULC only) on our website.
