JLJUI'HTir EEAHHATlaw GENERAL INDEX

Notes t

1. This General Index supplements the Combined Indices of the Manhattan District History, in Appendix C of this Volumei C(l) Index of Names of Persons; C(2) Index of Names of Agencies, Industrial Organizations, P ‘ r-J Universities, etc,

2, The items included in this Index are confined for the most part to general Bubjects end general headings only* for more detailed items, reference should be made to the indices which are included in the separate Books and Volumes of the History,

S. In most oases, the reference to a subject shows* first, the Book number (in Roman numerals)j then the Volume number (in Arabic numerals) and, finally, one or more Page numbers (in Arabic numerals). For example, the reference reading*

“Ac c i d e n t s "Electromagnetic Project "V, Vol. 4 - 3,7, 5,8, 5*12n

■will be found on Pages S.7, 8,8 and 5,12 of Volume 4 of Book V of the History,

4, References to Book VIII, Volume 2 (represented thus* "VIII, Vol. 2"), end to the Supplement to Book VIII, Volume 2 (represented thus* "VIII, Vol. 2 (Supp.)n), give each Page number by Roman numerals followed by Arabic numerals, because the Pages in these two parts of the History ere so num bered, the Roman numeral representing the Chapter number and the Arabic numeral representing the Page number in the Chapter. Thus:

"Aooi d e n t s "Los Alamos Project "VIII, Vol. 2 - 111-41, X7-S, XV-4n

will be found on Pages 111-41, I7-S, and XV-4 of Book VIII, Volume 2,

5, In some cases, the Section number (in Arabic numerals), and in some cases the Chapter .number (in Roman numerals) is inserted between the Volume number and the Page number (aB* "Sec, 2’* or "Ch,9w)j in references to Volume 2 of Book IV, which is divided into two "Parts”, the Part number (in Roman numerals) is inserted between the Volume number and the Page number (as* "Pt,!!"); in references to Book III or to Book VI, no Volume number is given, because these two Books of the History are not divided into Volumes,

6, When the referenced subject continues on several consecutive Pages (three or more), the reference usually Includes the number of the first of these Pages only, followed by the abbreviation "ff" (but in some cases, the reference is given thus* "5,12 to 5,17")j where the referenced subject con tinues in general through the whole of a Section or a Chapter, etc., the page numbers are usually omitted. u n i n Atomic Act 1946 •flTTV Specific, rioted Data v T A Cleara; red N 1 7. Wherever in this Index the reference "I, Vol. 14 (F'gn. Int. Supp.)" occurs (as, for example, under the entry "ALSOS Missions”) it is intended to mean Foreign Intelligence Supplement No. 1 of Volume 14 of Book I. Subsequent to the compilation of this Index, Foreign Intel ligence Supplements Nos. 2 and 3 to Book I, Volume 14, were incorporated in the History and at that time "Foreign Intelligence Supplement" was redesignated "Foreign Intelligence Supplement No. 1".

8. Because of the incorporation of the two additional supple ments, to Book I, Vol. 14, (Foreign Intelligence Supplements Nos. 2 and 3), the following entries are added(and references thereto have been inserted in their proper alphabetical positions in the main Index):

ADDENDA.
