Casey, I think that you can go about it either way. Academic resources are a bit different because there is already a filing system in place: LOC. You could just jot the call number down on it, and if you are using Endnote or some other reference manager, you can just look up the call number and go get it. Or, if you aren't using one of those, keep a txt file of the various journals etc. that you have photocopies filed for and their call numbers. Then, keep all that filed separately by LOC call number away from your "owner's manuals, bank statements, and newspaper clippings." If you think it helpful, you could also keep a "Personal" section in your academic files of papers written for classes and other people's papers or presentations for class. Keeping other people's work around (even if it's not published) would give me a great resource in the event I start work on the same topic. I can either raid their paper for bib info and to get a gyst of the arguments or I can just contact them together along the lines of, "Hey, remember when you wrote on Romans 14? Well, I'm working on it now, and I was wondering if you had any suggestions for background info and important previous scholarship." Such contacts can be extremely fruitful and time saving. Anyway, I'm rambling but I HTH.
