The Hinsdale Public Library is in the west wing of the Memorial Building.[1] It opened in 1893. The Memorial Building, the library's first permanent residence, was completed in 1929. D. K. Pearson, a director of the library association, donated his house and a portion of his estate to the library system; the donation funded a 1957 addition to the library.[citation needed]
