Why do librarians, historians, and scholars generally love microfilm? And yes, we love microfilm. We have comic books about microfilm.
Put simply: microfilm changed archives, historical research, records keeping, and overall scholarship the same way the internet changed scholarship 50 years later.
Microfilm last 500 years, is easy to store, easy to ship, and (once you're trained) easy to use.
Microfilm allowed libraries to scan unique material and share it will millions of people, and for the first time books held only by the British Library or the Library of Congress or Oxford University could suddenly be viewed all over the world.
For historians it's especially important: Many, many local newspapers have never been digitized and only exist in physical form. Many of these paper copies have totally rotted, so they only exist in microfilm.
There are 2 scanners in the main library.
Allen (main floor scanner, next to makerspace lab)
Bruce (Mail floor, near the microfilm cabinets)
This is an older machine, but is good for skimming. The two digital machines require a few seconds to focus every time you move the film, so it can take a VERY long time to skim. Bruce is not digital, so it's very easy to quickly skim. The scans, however, are directly to paper and not very good.
