xxxii EDITORIAL METHOD A descriptive note commenting on textual or physical characteristics of a document follows the designation of provenance. If a source from which one or more texts are drawn (e.g., a notebook or an official report) contains addi- tional material, that material is briefly described at this point such omitted material may be published elsewhere in the edition. Textual features such as original pagination and instructions to turn a page are silently omitted. The address and postmark of origin of a letter or postcard are given, if available. Original footnotes are reprinted at the foot of the corresponding page. Editorial footnotes, indicated by raised Arabic numerals placed in square brackets, follow the text and description of the document, unless the docu- ment is more than two printed pages in that case, editorial footnotes are printed at the foot of the corresponding page, separated by a hairline rule from the text and from any original footnotes. TRANSCRIPTION The aim of the transcription procedure is to maintain substantial faith- fulness to the original texts. No corrections, additions, deletions, or changes of characters, punctuation, or arrangement are made except as set forth below. Einstein wrote in Gothic script (deutsche Schrift) until 1905. We shall note his change to Latin script at the appropriate point in the chronological se- quence, but we print all of his texts in Latin type. A dateline is placed flush right above the text, regardless of its position in the original. Editorial additions or corrections to the dateline are in square brackets question marks follow uncertain parts of the dateline. The desig- nation circa, abbreviated "ca." indicates uncertainty within a few units of the designated day, month, or year. The dates of completion, submission, and publication of printed articles appear at this point, if known, together with the source of the printed version. Handwritten or typed letterheads are included printed letterheads are omitted unless relevant. A salutation is always placed flush left beneath the dateline and a first paragraph is indented. A closure is printed as one continuous text, and commas are silently provided in a closure where appropriate. Signatures are placed on the right and postscripts placed flush left beneath the signature. Einstein often used a handwritten abbreviating symbol for "and," which is transcribed as "&." The common German manuscript usages of "m" and "n," abbreviating the double consonants "mm" and "nn," are expanded, and the German double hyphen is rendered as a single hyphen.
