Wednesday, October 27, 1993 HALLOWE'EN must be near -- check out the observatory atop the Physics building, which has turned orange overnight and acquired a manic jack-o'-lantern grin. Among holiday festivities scheduled on campus, by the way, is a costume competition Saturday night in the Bombshelter pub in the Campus Centre. HAGEY LECTURE: Andrea Lunsford of Ohio State is on campus today and tomorrow as this year's Hagey Lecturer. Her major talk is at 8 tonight in the Humanities Theatre. Topic: "Intellectual Property in an Age of Information -- What's at Stake for the Academy". In other words, who owns ideas, what are the challenges universities and authors face in connection with copyright law, and what does the electronic world do to refereed journals? Admission to tonight's lecture is free; the Humanities box office has tickets. Tomorrow from 9:30 to 12, Lunsford will lead an informal session on literacy issues -- Needles Hall room 3001. POET'S COMING: Well-known Canadian writer Sandra Birdsell, who was writer-in-residence at UW a few years ago, will visit Conrad Grebel College next week and will give an informal reading Tuesday, November 2, at 8 p.m. in Grebel's board room. All are welcome. Chris Redmond Information and Public Affairs credmond@watserv1 ext. 3004
