The Center’s Local Government Records collection is part of the Illinois Regional Archives Depository (IRAD) system administered by the Illinois State Archives. The Regional History Center at NIU serves as one of the seven regional depositories throughout Illinois involved in preserving local public records and making them available to researchers. These records are older documents used by historians, genealogists, and local government officials. For more recent records contact the County Courthouse. Types of records available vary from county to county and may include: birth, marriage, death, naturalization, probate, and deed records. NIU IRAD housed records for the following eighteen counties: Boone, Bureau, Carroll, DeKalb, DuPage, JoDaviess, Kane, Kendall, Lake, LaSalle, Lee, McHenry, Ogle, Putnam, Stephenson, Whiteside, Will, Winnebago. Each depository has a computer generated listing of the records available in their facility and in the other six depositories throughout the state. This list and access to the available online databases can be accessed through the Illinois State Archives/IRAD website at: http://www.cyberdriveillinois.com/departments/archives/IRAD/home.html.
The databases available on the Illinois State Archives website for the records held by the NIU IRAD are:
Carroll County Birth Certificates Index, (1877–1913)
JoDaviess County Almshouse Registers Index, (1846–1938)
Kane County Circuit Court Case Files Index, (1836–1870)
Lake County Circuit Court Case Files Index, (1840–1898)
Ogle County Almshouse Register Index, (1878–1933)
