I'm scanning black and white photographs for a book which I'll be publishing in various formats (electronic and paper) later this year. Some of these photographs are 36 years old and are printed on some wonderful papers, such as Ilford Galerie, which are no longer available.
A high quality scanner and excellent software allow me to adjust the tonal qualities of some of the prints which I printed a bit too dark or too light. If I had the original paper I would print new photographs in the darkroom, but that's not possible. Using new papers would be the next best approach, but many of them do not have the rich, luminous character of Galerie.
I'm organizing and scanning every print I have, creating large files which will be adequate for any use. This also gives me the opportunity to work with each photograph, often seeing it in a new way. I may reprint some of them in the darkroom but I have so many new images to keep me busy there that I may never reprint images that I have worked with in the past.
Creating high quality scans from high quality photographs allows one to use the best features of film photography and the digital world. Consider it for your best images and the others as well. Then back-up your files and store the copies in at least two locations.
