A number of publishing professionals have announced big job changes today.

Sara Nelson (pictured, via) is leaving O, The Oprah Magazine to serve as editorial director at Amazon.com Books. Publishers Weekly had the scoop: “A spokesperson for Amazon said Nelson ‘will be leading our editorial vision for books in the print and Kindle bookstores on Amazon.com.’”

Parul Sehgal will be a new preview editor at The New York Times Book Review.

Agent, author and Kidlit.com blogger Mary Kole will join Movable Type Management as senior literary manager, to helm young adult, middle grade, and picture book properties at the agency.

Here’s more from Kole: “my new email is up and running. It’s MKole [at] MovableTM [dot] com! My submission guidelines remain the same as they were at ABLA: I want to see your query letter and the first 10 pages of your novel submission or full picture book text copied and pasted into the body of your email. The word “Query” should appear somewhere in your subject line. No attachments please (illustrators send a link to an online portfolio) and no snail mail.”
