There are several general categories of treaty research materials:
- full-text sources in print and/or online that provide the full text of treaties
- "finding tools," including print or online indexes, lists, and status tables, and also online websites and databases, that provide citations and vital information about a treaty and its status
- travaux préparatoires, the preparatory materials from the drafting, negotiation and adoption of a treaty
- commentaries, which print the treaty article-by-article with expert commentary on each article, possibly with citations to the travaux préparatoires and/or subsequent IGO documents, reports, domestic implementing laws, cases, or dispute settlements that show the implementation and application of a treaty.
The FAQs below are typical treaty research questions. Each question points to the treaty research materials that should help you answer that FAQ. This guide uses the term "treaty" as a shortcut for the various terms used for treaties, conventions, agreements, etc.
