Here are some upcoming Salt Lake City Library events:

Dewey Lecture Series: 300 Social Sciences — Dr. David Hilfiker, Main Library auditorium, April 7, 7:30 p.m.

In 1982, David Hilfiker left his rural practice in Minnesota to serve as medical director of Columbia Road Health Services in Washington, D.C. For a period of time, Hilfiker and his family lived in the shelter for homeless men, and he learned first-hand the conditions the homeless are faced with every day.

Hilfiker's book "Not All of Us Are Saints: A Doctor's Journey with the Poor" describes the state of the poor and ill in Washington, D.C., and Hilfiker's drive to change it. Free tickets are available at all city library locations.

Tickets for a private reception prior to Hilfiker's lecture are on sale at the Library Store at $40. Price includes priority seating and a signed book by Hilfiker.

Hunger Banquet, Main Library Conference Center, Saturday, May 4, 5:30 p.m.

One billion people live in poverty and more than 850 million suffer from chronic hunger. The Hunger Banquet will serve as a model for how the world's food resources are distributed.

This light meal separates participants into three groups: 15 percent receive a nutritious, upper-class meal; 25 percent receive a middling serving of staple foods and 60 percent receive a meager bowl of rice.

The Hunger Banquet is accompanied by a program about the factors in creating world hunger, those impacted by it worldwide and what can be done to help.

Registration is required, call 322-8131.
