The following scanned pages come from Everett’s personal copy of the original long version of the thesis. They contain examples of the modifications he made to the text in preparation for the inclusion of the long thesis in the DeWitt and Graham anthology (1973). The pages included here are those where Everett’s changes to the text affect its meaning. Notable among these changes are that Everett consistently changes “observers” to “observer states” (pgs. 356 and 360) and that he consistently strengthens his claims concerning the status of his derivation of probability (pgs. 359 and 361). The latter changes are particularly salient in the context of Everett’s disagreement at this point with DeWitt and Graham concerning the proper understanding of probability in the relative-state formulation. On the page taken from the second appendix (pg. 362), Everett substitutes the term “operationalist” for the term “positivist,” a change that did not appear in the printed version of the anthology. Note also the “language difficulty” footnote (pg. 363) and Everett’s “omit” notation in the left margin. This footnote did appear in the anthology.
