This museum has been around, in one form or another, for 40 years. And we have the files to prove it. Unfortunately, those files have been in various offices and organized in various ways for 40 years, too. So, pretty much, it's a big mess.
I've undertaken to (re)organize the files, using the office floor and a spread sheet style organizational system. It goes by decade across the top and topic along the side. The files out represent just a fraction of the total files.
I have recycled So Much Paper so far. Lots of old, irrelevant articles. Lots of multiple copies of memos or forms long out of use. Lots of paper taking up space which doesn't need to be here. So out it goes, keeping only what's relevant. Once this all gets organized by decade and topic, I have a stack of brand spankin' new file folders to put it in and put it away in an organized manner. ... and the stacks of files on the office floor will be gone!
