This week’s CAIRNS Etanhan Wotanin column is another in a series celebrating our 20th year as a nonprofit organization. The series is called “Twenty for Twenty” and this one connects the library built on the site of the mass-execution of 38 Dakotan men on December 26, 1862, with the Natural Library at Wingsprings and with CAIRNS’s Documentary Library. The column, “Twenty for Twenty: Libraries,” can be read now by clicking here, or later this week in the Lakota Times newspaper.
