Hi
skeeta!
This may not be the response you're looking for but I'll offer it anyway.
I love paper but I am also pretty tech savvy. My system currently includes a paper planner (using and loving Michael Hyatt's Full Focus Planner) but I also use Todoist, Fantastical, and Evernote for my lists and reference. It works for me.
I realized several years ago that I do my best thinking on paper. So I actually have written in a "How I Best Work" checklist "First think on paper, then move to the screen" to remind my how much better my work is when I plan stuff out on a page, rather than a word processing document.
The biggest issue with that is retrieval. Paper is good and all, but when I need to find exactly why I wrote, I need a system that allows me to access my handwritten notes quickly. I was able to solve that problem with Evernote's handwriting search feature. I can scan a piece of paper with my phone, save to Evernote, and then search for anything I hand-wrote. Works perfectly... for me. I think OneNote does this too?
However, I still like to sometimes go back and see the "original paper." So sometimes, I end up with "one page" reference material that does not fit into a larger category (just like what you're talking about, I think). I actually create a typeset label for whatever that item is and go ahead and file it alphabetically in my file system. Yup - even if it's just one piece of paper. So what? I need to be able to find it!
What happens more often than not is because I have a placeholder for that paper in my file cabinet, my mind subconsciously knows there's a place for similar items like that the next time I come across something similar. If the label needs to be updated, I know I can do that, too.
So... maybe if you tried creating a "solo folder" it could eventually grow into something larger?
If your concerned about space, how many drawers of paper reference do you currently have? Are you forcing yourself to work with too few drawers? Do you like the cabinets, folders, and labeler you're using? Is there something else in the chain that is causing you to resist other than space?
I started several years ago with 2 drawers. Then I realized I needed another. Then another. I am up to 5. To be honest, I don't think I will get larger than 5 drawers. That's my perfect number. I am pretty good about clearing these out every 6 months to a year and placing boring stuff in a Banker's Box.
I also create 1 1/2 inch binders of research material when I notice a folder getting too thick. For instance, I like to print cool articles for reference and place in a themed folder. Many of these start off with only one page in them. Eventually, my file cabinet is no longer the appropriate place for this -- so I'll move the stuff to a research binder and place it on my bookcase. Again, this works for me...
