I totally second Barbara. You could make high quality facsimiles and exhibit them instead of the originals (in that case, you should write it is a copy and not the original). But to attract people to the exhibits, it sometimes works to exhibit the originals for a short time first, replacing them afterwards with the facsimiles. If you do so, please pay attention that even if the documents are shown for a short period, the light levels should be adequate, since light damage is cumulative.
