Archives C3.8.1. The care and maintenance of these materials is important and may be an obligation for your museum. Papers, books, maps, etc. deteriorate rapidly in damp or high fluctuating temperatures. Aim at a storage environment between 13"and 18°C and rh of 50% to 60%, free of dust, chemicals or bright light.
SPECIMEN PRESERVATION PREAMBLE In this Part we discuss the ways in which specimens are kept safely, once collected, and enhanced by preparation. It includes sections on the preservation of field material in temporary storage (Cl), and on the complex subject of conservation (C2) including the processing of fossils and minerals (C2.2). This however is a vast topic, mostly beyond the scope of these Guidelines, and the tasks should not be undertaken by the unaware, the untrained or the unskilled. Publications exist which provide much information, for example Kummel & Raup (1965) or Rixon (1976), while the bibliography 'Geology in Museums' compiled by T. Sharpe (1983), provides lists of authors and subjects. The physical, permanent storage of specimens (C3) is vital to curation and these paragraphs should be read in conjunction with those on environmental control (C2.4). Also within this Part some suggestions are made on the ways in which specimens might be arranged in museum collections (C3.5), on collection security (C3.6) and on the storage and preservation of archives (C3.8). <strong>THE</strong> PRESERVATION <strong>OF</strong> FIELD MATERIAL IN TEMPORARY STORAGE Field-collected material in temporary store must be in weather- and pest-proof conditions. This minimum protection should prevent loss of or damage to specimens, field labelling, packaging materials and bags etc., through damp, fungus, insect or rodent activity. It may be advisable to incorporate a wide spectrum fungicide in collecting bags (if plastic) and plaster or polyurethane foam jacketed material during field packing to prevent fungal (including mould) growths, which might otherwise destroy specimens and associated field labels. Every effort should be made to reduce the length of time material remains in poorly protected conditions. Field collections containing unstable minerals or fossils, e.g. pyritic material, shales, clays, sub-fossil bone and hydrated or moisture-sensitive minerals (see C2.2.2.1) should be processed as soon as possible after excavation. Damp pyritic material, exposed to the air will, even over very short periods of time, decompose. Slow drying (over even a few weeks) of sub-fossil bone or enamel, some shales or clays and hydrated minerals may cause serious deterioration or loss. The uncontrolled drying out of hydrated materials can be prevented by artificially maintaining a high relative humidity (rh) environment around packages by double-bagging in polythene. SPECIMEN CONSERVATION GENERAL PRINCIPLES Geological material in the safekeeping of a museum is prone to decay. Conservation can be defined as embracing those measures which are designed to arrest or retard the deterioration of specimens by means of environmental
