From Wiegand's page on the FSU website (http://hott.fsu.edu/faculty/wayneWiegand.html).
Wayne A. Wiegand has been called "the dean of American library historians." His research centers on American library and book history.
Currently the F. William Summers Professor of Library and Information Studies and Professor of American Studies emeritus at Florida State University, Wiegand previously served as a professor in the School of Library and Information Studies at the University of Wisconsin-Madison from 1987 to 2002, where he was a founder and director of the Center for the History of Print Culture in Modern America. He also was a faculty member at the University of Kentucky.
A three-time winner of the G.K. Hall Award for Outstanding Contribution to Library Literature, Wiegand is a member of the American Antiquarian Society and served as director of the Florida Book Awards. In 2008-2009, he received a fellowship from the National Endowment for the Humanities.
Wiegand's vast catalog of books includes Right Here I See My Own Books: The Woman's Building Library at the World's Columbian Exposition (2012), Main Street Public Library: Community Places and Reading Spaces in the Rural Heartland, 1876-1956 (2011), Books On Trial: Red Scare in the Heartland (2007), Irrepressible Reformer: A Biography of Melvil Dewey (1996), "An Active Instrument for Propaganda:" American Public Libraries During World War I (1989), Politics of an Emerging Profession: The American Library Association, 1876-1917 (1986), and History of A Hoax: Edmund Lester Pearson, John Cotton Dana and "The Old Librarian’s Almanack" (1979). He has also authored or co-authored more than 100 scholarly articles and has edited collections of works on library history.
You can watch a Library of Congress video of Wiegand and his co-author, Sarah Wadsworth, discussing Right Here I See My Own Book here (because there are lots of intros, Wadsworth first appears at the 15:30 mark, and Wiegand makes his debut at 36:30).
