In this video, Book and Paper Conservator, Ashleigh Schieszer, and Sr. Conservation Technician, Catarina Figueirinhas, are carefully lining an 1863 Cincinnati business map (from the Public Library's collection) with kozo fiber tissue.  They had previously removed the prior cloth lining and the residual adhesive from this lining by washing the map and mechanically removing the adhesive.  They also humidified and locally flattened the map to try to reduce creases caused when the map was previously lined with cloth.
