The State Library's Preservation team have put together a number of fact sheets on preservation which may be useful for family historians. The topics include: Caring for paper-based materials Caring for photographs Dealing with mould Drying a wet book Removal of smoke odour Storage of newspapers Also contacts for related suppliers and preservation related websites. You will find them at http://www.sl.nsw.gov.au/about/collections/preservation/index.html Cheers Michelle Nichols
