E D I T O R I A L M E T H O D l x x x i x Letters Letters written by Einstein are titled by the name of the recipient. Letters by others to Einstein are titled by the name of the author. Einstein’s name as author or recip- ient is omitted. For a particular date, outgoing letters by Einstein are presented first, followed by incoming letters. They are presented in alphabetical order by receiver and sender, respectively. For Einstein’s outgoing letters, the recipient’s address is placed in the descriptive note. For incoming letters, all handwritten, printed, or typed letterheads are placed in the descriptive note. If address information is repeated at the foot of a document, it is omitted from the transcribed text. Printed information on an otherwise hand- written document or on the verso of a postcard is generally omitted. A dateline is placed flush right above the text, regardless of its position in the original. When the author omitted a dateline, the date is provided from either post- marks or from other contextual information. Editorial additions or corrections to the dateline are placed in square brackets. Date uncertainties are indicated by ques- tion marks. The designation “circa,” abbreviated “ca.,” indicates uncertainty within a few units of the designated day, month, or year. The salutation is placed flush left beneath the dateline, and the first paragraph is indented. The first word in the first paragraph is usually capitalized. Each letter is followed by a descriptive note that consists of the following: (a) A descriptive symbol (see Descriptive Symbols, pp. c–ci) (b) the location of the orig- inal, in parentheses. (If no provenance is specified, the source is the Albert Einstein Archives at the Hebrew University in Jerusalem if the location is unknown, the source of the photocopy or transcript is given. For symbols of documentary repos- itories, see Location Symbols, pp. xcvii–xcix) (c) previous publication data (d) the call number assigned to the letter in the Albert Einstein Archives, within square brackets (e) a transcription of the letterhead and the addressee (f) a note comment- ing on textual or physical characteristics of an original when they affect legibility— whether it is cropped, perforated, obscured, or incomplete. (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 the omitted material may be published elsewhere in the series. Textual features such as original pagina- tion and instructions to turn a page are silently omitted) (g) for postcards or if an envelope is available: a transcription of address and sender lines, as well as a de- scription of the postmark or docketed postmark if the date cannot be established otherwise.
