Good find: Reader Digest's American usage dictionary from 1983

While moving my grandmother's belongings during her relocation, my mother found this like-new Reader's Digest usage dictionary from 1983. It has more than just usage, though; it is also a neat linguistic resource that explains many linguistic concepts, groups English loan words under the languages from which they were borrowed, and lists unique words from different American dialects.
