In 2010, SDC was selling a book entitled "50 Years of Making Memories, Photos that capture our times together." Info on the copyright page says, "Copyright (c) 2010 by Springfield News-Leader, Library of Congress Control Number: 2010906853, ISBN: 978-0-9826428-8-1, Written by: Jan Peterson, Layout by: JE Cornwell & Carolyn Cambronne, Published by: JEC Publishing Co., Printed in Canada."
In 2013, SDC still had copies for sale at numerous locations, including the Hospitality House and the General Store. So, they still have copies from 2010 or it has been reprinted.
