Noted: Sandi Torkildson, who helped found A Room of One’s Own in 1975, has invited a representative from the UW-Madison Center for Cooperatives to give an informational presentation Tuesday at 7:30 p.m. at the bookstore, located at 315 W. Gorham St. Torkildson, who announced in June that she was putting the store up for sale, said she has had several customers inquire about the feasibility of a co-op, but there was no organized effort. The meeting is simply a way to bring those interested in a co-op model together and to learn about that type of business model.
