What method do people use to organize their research materials, meanining, books, articles, etc? Having just survived another impressive avalanche of materials, I am thinking about what I can do. I am in an office that has limited options for me, its essentially borrowed space, so I am not in much of a position to make waves about storage--and I have it to myself! Other than (un) tidy piles of things, what sort of organizing methods do people use? Before, at home, I had all sorts of storage room, and now am trying to figure out a new system...
