Greek Letters (1.0E. Language and script of the description )
Romanize all occurrences of Greek letters regardless of the facilities available (the intent is to assist filing (by persons or machines) and searching (machine) although there are characters for alpha, beta, and gamma in the character set) and although certain Greek capital letters are identical to their roman equivalents. If the context shows that a Greek letter or letters is used to represent a letter in the Internal Phonetic Alphabet, however, see the section on Special Letters, Diacritical Marks, and Punctuation Marks .
If the letter appears separately, give the name of the letter in the language of the context (if unknown in the language of the context, use English) enclosed within brackets. For searching purposes, insure that the bracketed interpolation is not connected with other letters. Thus, if no space appears in the source on either side of the Greek letter, put a space on either side of the bracketed interpolation, except when this interpolation is already distinct from adjacent letters by the presence of characters that serve as separators. N.B. This provision is necessary, because brackets do not serve as separators for searching purposes. (FN 1 )
When a Greek letter is used in a word that is otherwise in the roman alphabet in the source, use the romanized form of the letter (instead of its name) in brackets.
