The papers of the Kathmandu Valley Preservation Trust are one result of the passion of Harvard University Professor Emeritus Eduard F. Sekler. In the 1960s he witnessed the encroachments of progress and the associated threat to buildings in the royal and religious centers of the Kathmandu Valley in Nepal, and co-founded the Trust in 1990 with others interested in documenting the sites and restoring the buildings. The Trust has restored numerous temples, guesthouses, townhouses and shrines in Kathmandu, Patan and Bhaktapur, and in the process has generated vital documentation including measured drawings, photographs, contextual materials, planning reports and feasibility studies. Threats to this material from the natural environment and political turmoil, as well as longstanding ties to Harvard of several of its members, led the Trust to approach the Frances Loeb Library at the University’s Graduate School of Design, where as a result the archive will be housed. The infrastructure developed by Harvard University Library will be used to create a virtual archive available worldwide on the web, as well as a parallel paper archive to be maintained by the Trust in Nepal.
