I agree, I think these professional archivists are letting perfect be the enemy of good enough. There is no real reason they couldn't give a large team of interns armed with smartphones a crash course in how to turn the pages of a book without tearing them and set them loose digitizing entire libraries in days; then afterwards they could take their time with their high powered x-ray 10 gazillion dpi scanners or whatever the hell they'd like to use.

What we're seeing from archivists is a prime example of gatekeeping and job security.
