Scholars haven’t done much with Updike’s children’s books, but blogger Maria Popova (“Brain Pickings”) notes that Updike’s A Child’s Calendar, originally published in 1965, was updated for a 1999 re-release to be more racially inclusive.

Trina Schart Hyman’s illustrations feature mixed ethnicities that were absent from the original book. Popova observes that Updike even made slight changes to the text in order to “celebrate diversity,” and cites examples.

Here’s the article—“A Child’s Calendar: John Updike’s Vintage Children’s Book, Updated to Celebrate Diversity”—with poems and illustrations.
