At the Mercer County Historical Society in Aledo, IL, the Genealogy Division, organized in 1979, has accumulated a large collection of Mercer County material for research purposes. Volunteers will assist in answering queries by email, letter, or a visit to the museum. A reader/printer is on site.
Opening the museum for research at times when it is normally closed is at the discretion of the curator, and the curator may refuse such a request. The length of time that research will be allowed is also at the discretion of the curator. There will be a charge of $15 for up to one hour of research, then $10 per hour after the first hour, payable to the Mercer County Historical Society on the date of the requested opening. Contact the curator, Nancy Hessman, to inquire about opening the museum for research.
