Documents describing the negotiation and drafting of a treaty are referred to as travaux préparatoires. As when locating drafting history materials, researchers seeking these preparatory materials are wise to first search for a compiled travaux préparatoires, either online (see example), or in print, and if one is not available, turning next to secondary sources that may discuss the treaty's drafting. If these time-saving resources are not available, or the researcher wishes to consult additional primary documents, identify any conference at which the treaty was discussed, and search for print or electronic records of the conference proceedings.
