What else is going on

Congratulations to the Sherlock Holmes Collections at the University of Minnesota, celebrating its 50th anniversary during the collections’ triennial conference July 26-28 at the university, presented by University of Minnesota Libraries, Friends of Sherlock Holmes Collections and Norwegian Explorers of Minnesota. The collections house the world’s largest gathering of material related to Sherlock Holmes and his creator, Arthur Conan Doyle, with more than 60,000 items, including books, journals, and a variety of other forms that trace the transformation of the Holmes character from the printed page to a cultural icon. The sold-out conference will bring 170 attendees to the university, some as far away as the United Kingdom and Japan. In celebration of the golden anniversary, the public is invited to a free exhibit of 50 objects outlining the history and development of the collections as it seeks to be the world’s center for the study and appreciation of Holmes in literature and popular culture. Each piece tells a part of this story, including the first appearance of a Holmes adventure, manuscript leaves and letters in Arthur Conan Doyle’s hand, original illustrations, posters, and sculpture, seldom-seen albums and ephemera, and new acquisitions. The exhibit will be up until Sept. 20 at the Elmer L. Andersen Library, 222 21st Ave. S., Mpls. Hours are 9 a.m.-5 p.m. Monday, Tuesday and Friday, 9 a.m.-6 p.m. Wednesday and Thursday.
