Today's treasure chest for me is the The Lucas County Genealogical Society. Throughout the years, they've helped without me even asking for it. Now they do look-ups from this index of all newspaper articles. http://www.chariton.lib.ia.us/use-the-library/genealogy2/npindexmain
I just ordered 36 articles and know how much it cost me? $36.00. Once I get them, they will have filled my chest with treasures.
They also have wonderful blogs filled with great articles about the county's history.
I (heart) the Lucas County Genealogical Society of Iowa.
