Welcome to the world of collecting!
Years ago, I found an old green three-drawer filing cabinet in an antique/junk shop. Not one of the new, flimsy ones, but a built-like-a brick-outhouse job from the 40s or 50s. It was one of the best five bucks I ever spent. She's not pretty, so I put it in a closet (you've seen it, Fran!), but it does its job.
My job, or course, is a slightly different story... It's full of folders (some properly marked, others not) that keep growing. Then there are "files" that haven't yet made it into the cabinet. For instance, there's a stack of U.S. Patents (all horn cranes/supports) on top of the file cabinet that are awaiting a proper folder. But they can't go in until I free up space in a drawer currently filled with photos...
So the moral is that a system is only as good as you make it!
In the file cabinet I have a file for "Reproduction Edison Documents" and into this go all the Edison catalogs, fliers, etc. that are copies. (Originals of anything go safely into drawers in a cylinder record cabinet that lost its pegs.) There's another file for "Reproduction Columbia" and another for "Reproduction Miscellaneous." Where's "Reproduction Victor?" Well, years ago I kept all the repro Victor/Berliner materials on the shelf of a book case, and that's where they remain. Why don't I just add a "Victor" file to the file cabinet...?
I keep my paper copies of
The Talking Machine World in large manila envelopes in shopping bags. Now that the TMW is available online, I don't need these as much, but it's still fun to occasionally curl up in a comfortable chair with them - - after all, who wants to clean out that file drawer?
Paper copies of
The Phonoscope are arranged on a bookshelf...
Paper copies of
The Columbia Record are laying in a record packing crate...
My collection of many hundreds of original advertisements are in marked cloth binders that cover about 5 linear feet of space in the lower portion of an old wooden display/storage cabinet...
As you can see, there's little rhyme or reason to my "system," but I know where everything is...
My advice (which I didn't follow myself) is to devise a workable, sensible system; set it up, and stick to it!
Good luck - -
