INDEX Italic page numbers indicate references to front matter, or to editorial notes. Page numbers followed by a lowercase "n" indicate footnotes to Einstein documents. References are collected under the appropriate English heading. "Albert Einstein" is abbreviated to "AE" in subentries. Correspondence cited in editorial material is listed alphabetically by correspondent/recipient following the words "correspondence with" (referring to a group of letters exchanged with AE) and/or "letter from/to" (referring to specific letters). A separate index of citations follows the main index.
