²⁰ Personal correspondence and/or interviews with document librarians at Berkeley, Stanford, U.G.L.A., Los Angeles County Law Library, Harvard Law Library, United Nations Library and Library of Congress. On the West Coast by far the largest foreign treaty collection is at Los Angeles County Law Library but its Foreign Law Librarian, Dr. William Stern, wrote on June 3, 1965: “The biggest gap in our international law collection is in the field of treaties.” The U.N. Secretariat has informed me that there is no plan to update its admittedly obsolete 1956 List of Treaty Collections in the foreseeable future. Definitional problems preclude accurate figures but a reasonable estimate of the consensus of the above experts suggests that national treaty records are currently being published in less than approximately 50 foreign countries, and that only approximately one-third to one-half of them are available in full through the above libraries.

²¹

• a)

  a) Letter dated March 3, 1965, requesting name and address of treaty officer in national foreign ministry, sent to Washington embassies of following countries: Austria, Belgium, Canada, Czechoslavakia, Denmark, El Salvador, Finland, France, Germany (Fed. Rep.), Greece, Guatemala, Hungary, Iceland, Ireland, Israel, Italy, Luxembourg, Mexico, Netherlands, Norway, Poland, Portugal, Spain, Sweden, Switzerland, United Kingdom, U.S.S.R., and Yugoslavia.

• b)

  b) Reply received from all the above except the following countries: Czechoslovakia, El Salvador, Guatemala, Hungary, Poland, and U.S.S.R.

• c)

  c) Letter and questionnaire dated June 22, 1965, regarding gaps between UNTS and national treaty records sent to treaty officers of the same countries as listed under Item (a) above.

• d)

  d) Reply received from the following countries only: Canada, Denmark, Finland, Iceland, Israel, Portugal, United Kingdom.

• e)

  e) Treaty officer visited personally in the following countries in the spring and summer of 1965: Belgium, Canada, France, Netherlands, Spain, Switzerland, United Kingdom, U.S.A., and at International Law Commission in Geneva, Israel and U.S.S.R. Most of the treaty officers of these countries have agreed in principle to co-operate in investigating the extent of the gap between UNTS and their national treaty records.

• f)

  f) Detailed, repeated exchange of information and close working relationship with treaty officer of only one country so far, i.e., Canada, April to June 1965; see also supra note 1.

²² See Table 1. The figures in the bottom line would suggest a much higher average. However, the world average shrinks as a result presumably of the small gap of the world’s top treaty maker, i.e., the U.S.A. See Table 7, Column 1, for a ranked listing of the world’s top twenty treaty makers.

²³ See footnote on Table 1.

²⁴ The usefulness was measured by the number of treaty partners which each of the five tentative test countries showed on the country profile printout, as follows: U.S.S.R. 50, Canada 49, Switzerland 41, China 38, Guatemala 15 and Venezuela 12.

²⁵ The formula for all possible pairs in a given set of items is: X=(n²-n)/2. The number of treaty-making entities in the UNTS is 159 (122 states and 37 international organizations). The world total of possible treaty pairs is (159²-159)/2=12,561. Of course, many possible pairs of entities do not in fact have any mutual treaties at all and many other pairs have very low scores of from ι to 5 mutual treaties. For this immediate purpose, only the pairs with 35 or more mutual treaties are shown in Table 4 below.

²⁶ See Table 4, All Pairs of Parties With at Least 25 Mutual Bilateral UNTS Treaties.

²⁷ See Table 7, Line 13, Columns 7 to 11, showing the general trend of the Canadian treaty volume against which the gap is gaining slightly.

³⁴ The topical categories of Table 5 are taken from the Canadian Treaty Series and the Rohn Printouts, respectively. In matching them for comparative purposes, some minor adjustments of content and language have been unavoidable. The adjustments do not affect the magnitudes involved. For a ranked listing of the major categories and sub-categories of the Röhn Printouts, see Table 9. Code 4.1 concerns air transport.

³⁵ See Table 6, Column a, and Table 7, Column 1.

³⁶ Only bilateral treaties are used in arriving at the American preponderance but multilaterale would probably change the result only in a very small degree, and possibly even further upward. For further details, see Tables 4 and 6.

³⁷ I am indebted to Ambassador Shabtai Rosenne of Israel, Member of the International Law Commission, for persuading me to extend my inquiry from the fact of registration to the act of registering. The material in Table 6 would not have been organized in this particular way without the imaginative train of thought he developed during a conversation in Geneva in July 1965. See also supra note 32.

⁴⁷ One of my research assistants, Mr. Guy Poitras, combed through 6 volumes of the International Law Commission Yearbook for magnitude-oriented remarks on the law of treaties. His most inclusive count reached 656 items. Among the most relevant items are, e.g., Scelle, 1950, at 81, Sec. 72: “…treaties concluded by international organizations were still few in number, but this could and would increase.” Or, Tabibi, 1964, at 74, Sec. 9 : “…the trend towards more general participation in multilateral treaties was gaining momentum.…” The secondary literature abounds in comparable statements. E.g., McNair, op. cit. supra note 15, writes that “a glance at the index of the United Nations Treaty Series will show” certain agreements to be “now becoming very common” or, at 751, that certain treaties are “steadily increasing in number.” Further examples in Rohn, , “A Legal Theory of International Organization,” 5 Turkish Yb.
