When I began my genealogical research, photocopies faded within a few years. They were not meant to be even reasonably permanent and the concept of archival photocopies was laughable. The librarian warned me that I would need to transcribe by typing any copies I had made on their photocopier.
Copiers of those types are not found any longer, but do you have materials that might fade with time?
Are there records or family papers that should be reproduced before the ink seemingly evaporates from the page?
