5. Page 17 has a table of "oldest authentic centenarians", which gives John B. Salling as 113 years and 1 day. However, page 196 has his age as 112 years and 305 days. In a letter from Norris McWhirter, he gave this explanation:

   "We received advice that John B. Salling was, in fact, some months older than we had earlier been informed by the Veterans Administration Bureau in Washington. The first 32 pages of the book are printed after some of the later sections, and we amended it in the only place we could during the course of production."
