xxxiv EDITORIAL METHOD Reference to a text in the already published volumes of The Collected Papers is made by document and volume number (if in another volume) except for Einstein's published papers, which are cited by author and date. The surnames of certain persons who figured prominently in Einstein's life are printed in small capital letters in all editorial matter to indicate that short accounts of their lives are included in the Biographies that appear at the end of all Correspondence volumes, as well as in this volume. Bibliographic references in all editorial matter are given by author/date citations. These citations are listed alphabetically in the Literature Cited sec- tion at the end of each volume, where full bibliographical information is given. The lists of literature cited will not constitute a bibliography of all significant works on Einstein.
