The Round Lake Library was established in 1897 by the Woman's Round Lake Improvement Society (WRLIS), a not-for-profit organization of men and women from the community who sponsor activities to improve the village. The mission of WRILS was "to make Round Lake desirable and attractive as a place of residence and in all ways to study to keep pace with the progressive spirit of the age." The Round Lake Library has stayed true to WRILS' mission and is a beloved centerpiece of the Round Lake community that has thrived for the past 110 years.
