I believe most countries allow making archival copies - either digital or physical, and sometimes both - of a whole publication of any sort. The fair use aspect of archival is the preservation of the contained information under the assumption that it won't see the light of day, except for if the person or party making the archive needs to reference it in some way (such as for writing a paper), or once the publication in question enters the public domain. I'm not a lawyer, so check your local laws, but I know that such a thing has happened for the BBC's Doomsday programme in order to save it from laser disc rot, so one can only assume that this logic applies to other things.
