Prepared by the Office of the Legal Adviser at the U. S. Department of State, the "Digest of United States Practice in International Law" is an annual compilation of documents and commentary highlighting significant developments in public and private international law. The compilation is an invaluable resource for practitioners and scholars in the field.

Each annual edition compiles excerpts from documents such as treaties, diplomatic notes and correspondence, legal opinion letters, judicial decisions, Senate committee reports, and press releases. All of the documents excerpted in the Digest are selected by members of the Legal Adviser's Office of the U.S. Department of State based on their judgments about the significance of the issues, potential relevance to future situations, and likely interest to practitioners and scholars. In almost every case, the commentary to each excerpt is accompanied by a citation to the full text. - Davis Robinson: Former Legal Adviser to the US Department of State.
