It is tempting to simply scan all this. My Only concern would be to choose a common or open format. My father collected “sky and telescope” the premier magazine for astronomers. He had a collection that spanned back to the origins in 1941. Just missing a few during the WWII years lost to the mists of time. His collection was about 19 feet long. He traded it for 7 dvds. Alas, the reader software stopped working with windows 10 and 11 and a lifetime of collecting has been lost to him.

Point is. If the donation was digitized in PDF or similar it might not be so bad that the atoms were lost. But now it seems lost forever which is a shame.
