It is remarkable just how many publications he generated. This is a man who physically cringed when a sentence of his was revised even a small bit. How did he stand it when editors haggled and hassled over his writing? The obvious answer was that the payoff, i.e. publicity, was worth the pain. Right?
       Interestingly, his first publications were true stories about hunts which were published in Alaska before he went to Harvard. That is a measure of his determination to be published.  These articles are talked about here.  In addition to the descriptions that he did of dinosaurs which are listed here, he published these articles, several while he was at Harvard with Dr. Romer and later, the remainder at BYU:

     after him, mom would remind him that this one had a little tiny brain.)
