Our staff attended the Spring meeting of St. Louis Regional History Organizations at Jefferson Barracks today to discuss plans for a big event we will be attending in June, and to network with historical orgs from all across the STL area. It was a great opportunity to share information about the library and learn how we can support all of the groups who are actively preserving our history. You’ll be hearing more about the June event as it gets closer, but mark your calendars now. There are currently over 50 history organizations signed up to participate!
