MOLD ALERT! Most of the collection was severely contaminated with mold when it was deposited at the Clarke. Processing was delayed until fumigation could occur. Those boxes were fumigated in Skokie (Ill.) in summer 1999. Other, later donations do not appear to be severely contaminated with mold, but patrons should be careful when using these collections.
