This is an attempted cross-post: I have a reference to Neevel, Johan G. "Exposure of objects of art and science to light from electronic flash-guns and photocopiers" _in_ _Contributions of the Central Research Laboratory in the Field of Conservation and Restoration_ (Amsterdam), 1994, pp. 77-87. Our ILL people tell me that none of the small handful of holders they could find on OCLC would supply a photocopy. Help! Henry Grunder Conservation/Preservation Coordinator The Library of Virginia
