Published since 1879, the Wisconsin Blue Books comprise a veritable treasure trove of information about the Badger State. Recently, the University of Wisconsin Digital Collections group digitized all of the Blue Books from the first volume up to the 2003-2004 volume. Within each volume, visitors can browse the complete contents, which include U.S. Census statistics, election statistics, information on state finances, and biographical sketches of various persons within the state. Visitors may also wish to perform a more detailed search across all of these volumes, or they can also use the table of contents for each volume to hone in on different topical areas of interest.
