Whilst googling myself the other day, I came across this post on the First Person Irregular blog, written John Ochwat. Now, John seems like an intelligent guy and he's entitle to his opinion but . . . he is clearly in need of more interesting pursuits in his life.
In his post, John opins about the evils of the author bio being longer than the text in children's books (yes, he counted them). He uses Good Morning, Garden, written by Barbara Brenner and illustrated by myself as an example. Ouch! He even shows the lovely cover (and thank you for that, if you're going to slam a book, you can at least have it look good and sell a few copies, right? But I digress.) He even complains that there are duplicate bios on the back page and on the jacket flap, making the text to author bio ratio something ridiculous like 1:2.
Here's the point, John: the text and author bios are written for two different audiences. The text is written for the kiddies, or to be read to the kiddies. The bios are written for the adults who buy and read the books to the kiddies. A few adults actually find them interesting. In a small way, it gives additional resources for the teacher using the book in the classroom. So please, take a deep breath. There must be worser evils in the world for you to cast your eye upon.
