We talk a lot about archiving stuff - great, but I hardly see the same emphasis on finding things. Search is equally important because thats where the rubber meets the road - actual utility of archive is realized and benefits of long term archives are reaped. Of course, there are queries such as "Find all newspapers for July 26, 1931" if something important had happened on that day - this would be an O(1) query for a library if they've indexed newspapers by date. Finding all mentions of "Bankruptcy of Cooks Mills in Lawson, Texas in 1931" is much harder problem if it is a physical storage. I'd be ok with converting all newspaper archives in digital format that's searchable.
