A kids’ magazine that has focused on Iowa history for a quarter-century is ending its run while its publishers determine how to move forward. “The Goldfinch” has been putting out four issues a year since 1975, targeting children in grades four through eight. The company wants to reach its readers besides subscription based publication.Tom Morain is administrator of the State Historical Society of Iowa, which publishes the magazine. He says Goldfinch subscribers have dwindled to below one-thousand and the final edition will be printed this spring — until a better plan is developed.Morain says the 24-page magazines always deal with one subject at a time. Over its 25-year run, coming out four times a year, he says back issues of the Goldfinch are now a treasure trove of timeless historical information about the state. Goldfinch magazines range from Civil War to Iowa Caucases.Subscriptions had been running nine-dollars for three issues.
