On July 31st, the SCLC 39 proceedings were published. The papers that appear in this volume contain representatives of various Siouan languages from different parts of the United States. The topics ranged from lexicography to folklore to morphosyntax, and were a great representation of the diverse subjects of inquiry that we typically see at the SCLC.
The proceedings are available here: siouan.org/proceedings/sclc39.
