Although I'm not in favor of banning books, I do have a simple guideline: "If there is anything virtuous, lovely, or of good report or praiseworthy, we seek after these things." (Articles of Faith 1:13). Coupled with that is D&C 88: 118 "...seek ye out of the best books words of wisdom; seek learning, even by study and also by faith."
In my book, that includes quite a spectrum, ranging from Calvin and Hobbes to, yes, textbooks. Rats.
I've been cartooning since I was a teenager, and have been published in magazines ranging from AASHTO Quarterly to the New Era and several other periodicals, trade publications and newsletters.
