Wayne Wiegand is a prominent expert on public libraries who titled his book, published this fall, Part of Our Lives: A People’s History of the American Public Library.

How big a part of our lives are libraries? Wiegand summed up key themes of his book by telling a conference at Marquette Law School on Thursday that libraries “are much more important than we previously thought they were.” They are vital parts of boosting the lives of millions of people and of America as a whole.

Those were key themes also of the packed-house, half-day conference, titled The Future of the American Public Library, in the Appellate Courtroom of Eckstein Hall. Leading figures on the past and future of public libraries in America and in Milwaukee specifically described the past, present, and future of these often low-profile but central pillars of American life.

The conference had an underlying tone similar to a pep rally for libraries. Many in the audience were themselves librarians who applauded the depiction of libraries as places that adopt to and serve important community needs — inspiring young people, providing valuable information to everyone from job seekers to the curious, bringing together neighborhoods, and sometimes providing warm, reassuring places to those who need them.
