His passing was noted in the local and state-wide newspapers and with prominent obituaries in the New York papers as well as in the national press. He is interred in Morningside Cemetery in Gaylordsville in the Newton family plot next to Dorothy. In 1962, Rex's nephew, Milton E. Brasher, published his biography of Rex. The information on the title and copyright notice pages of this set lead the reader to believe that it is a modern reproduction of the original 1932 twelve-volume set. However, some subtle editing has been done to compress the size of the monumental work to something more manageable.
Prints are on both sides of a page with the name of the bird printed thereon.
All text is grouped at the back of the book eliminating inefficient white space. There are no tissue interleaves required between the pages as in the 1932 work. Finally, some plates have been retitled to conform to modern naming conventions. On the other hand, the original 1932 work revealed a different count. Thus there is some disagreement in numbers.
