9 SUMMARY

What continue to be nemeses in the treatment of works on paper? Overall consolidation of cleavage, the treatment of mold, the lack of completely satisfactory nonaqueous adhesives, and the costs of treatment deserve attention. For the best review of developments in treatment, readers are encouraged to consult Paper Conservation News and Institute for Paper Conservation Annual from Great Britain, Restaurator from Denmark, Abbey Newsletter from the United States, and the American Institute for ConservationBook and Paper Group Annual and Paper Conservation Catalog.

In addition to those topics brought to readers' attention in the papers in this issue on scientific research (van der Reyden 1992) and treatment in libraries and archives (Fredericks 1992), the developments in treatment identified as most current are, in summary:

• a quality of research by conservation scientists that ventures some qualitative and quantitative guidelines about procedures and materials in actual use
• an appreciation of systematic gradations of treatment
• pulp delivery
• a concern for the long-term effects of local treatment procedures
• a greater understanding of the practice and traditions of Japanese mounting
• accepting limitations on treatment due to tailored storage and a concern for the preservation of format
• expanding the criteria of judgment about what constitutes good and appropriate treatment in the care of large individual works and large groups of objects.
