The purpose of the manual is to systematize the material on the problem under consideration and to acquaint students with the features of the American version of the English language, its differences from the British version. Differences are considered in such aspects of the language as spelling, phonetics, grammar and vocabulary.
Book is not OCRed, so cannot be copy-pasted from (and is fuzzy/piixelated enough that OCR would probably not be very successful).
