>unfamiliar with archival process
If you're interested in archival process as a whole you may look at some guides online like https://dag.cessda.eu/Chapter-1/8-What-is-the-process-of-archiving-from-beginning-to-end
If you're asking about your specific task at hoof, you should be more specific. In general, I'd get good camera/flatbed scanner and dump it on DB with attention to tags. Remember, archival process ends only when you made your information available for public in manner that helps to find and navigate that information. Until then it's just another lost media.
