l x EDITORIAL METHOD
In the case of typed documents, all typographical errors are retained; but in the
case of overstrikes, the spacing is conventionalized in all cases.
In the dateline of outgoing letters, the Berlin street address is omitted.
Towns and cities underlined in addresses at the head of documents and on enve-
lopes and postcards are rendered in roman font.
When two parallel dashes (short “equal sign”) are used for indicating a hyphen,
they are rendered as a hyphen.
The German dash is used to indicate the end of a paragraph; the subsequent line
is indented even if the author does not do so in the original text.
Einstein often used a handwritten abbreviation symbol for the conjunction
“and,” which is transcribed as an ampersand.
Abbreviating the double consonants “mm” and “nn” by placing a bar over the
single consonant is not followed. In cases where the author has used an almost
shorthand form to designate the endings “ung” and “ungen,” the word is transcribed
in its full form.
The use of “J” for “I” in typed originals or transcriptions is rendered in its mod-
ern usage “I.” As Einstein does not differentiate between a Latin “I” and a Gothic
“I,” both are rendered in Latin.
The older convention in German of writing an adjectival indicator of a proper
name separately from the name itself is modernized: for example, “Tetrode’sche”
is rendered “Tetrodesche.”
Where an author does not provide a hyphen for a word that is broken in the orig-
inal at the end of the line and the beginning of the next line and there is no capital-
ization of the first letter on the next line, the word is transcribed as if it were hy-
phenated.
Where lack of punctuation might prove confusing in understanding a passage,
an extra space is left in the text.
When part of an equation is canceled for calculational purposes, it will be noted
by a diagonal line running from the upper right to the lower left to differentiate it
from a deletion.
Superscript and subscript interlineations are brought down to the line; interlin-
eation is noted when significant.
Where quotation marks are introduced in idiosyncratic fashion, their use is con-
ventionalized.
Where Einstein uses a superscript and an * for the same purpose, it is uniform-
ly rendered as *.
Spaced type (“Sperrdruck”) in the original is rendered in italics unless it occurs
in proper names, in which case it is rendered in roman characters. Proper names
rendered in small capitals in the original are changed to first-letter capitalization.
