The main sources of information for this study have been the published and mimeographed documents of the League of Nations and the United Nations system. Foremost among these have been the reports submitted by the key drug organs at the end of each session to a higher body. In the text we have referred to these in an abbreviated way, as these examples show.

CND: 23d, 1969    Report of the twenty-third session of the Commission on Narcotic Drugs in 1969.

PCB, 1960    Annual report of the Permanent Central Board to the Economic and Social Council on the work of the Board in 1960.

WHO/EC DD, 1969 Report of the WHO Expert Committee on Drug Dependence, published in 1969. (Reports of the expert committees are usually published in the year following their meetings.)

In our reference to mimeographed documents we have fepro-duced the official UN documents series symbols. These identify the issuing organ and the document type. Thus, documents of the Commission on Narcotic Drugs bear the symbols E/CN.7/ . . . , while General Assembly and ECOSOC plenary documents are prefixed by the symbols A/ . . . and E/ . . . respectively, followed by four digits. The symbol series E/CONF.63/C.1/SR.4 indicates that the document is the Summary Record (SR) of the 4th meeting of Committee 1 (C.1) of the plenipotentiary conference on amendments to the Single Convention (E/CONF.63/ . . . ).

The symbols used by the League of Nations denote the body to which the document was distributed, its date and number. The letters A, C, and M refer to the Assembly, the Council and the League Members in general, while the initials OC and CH refer to the Opium Committee and the Health Committee (Comité d'Hygiène).
