I bought this book when I was buried in papers and had a chaotic filing system. I was attracted to the subtitle, "A Proven Filing System for Personal and Professional Use," and not wanting to reinvent the wheel, decided I would faithfully follow this system step-by-step for a month. If I didn't like it, I didn't have to stick with it. That was more than 10 years ago. I followed her easy 5-step plan and it works beautifully. It only looks complicated when you skip around the book.
Recently, I had some furniture delivered to a consignment shop and the store owner called and asked if I could possibly find my original receipts. I told her to hold a moment, and within seconds, pulled the receipts from my files and told her how much I paid. She said, "You must be a very organized person to have found those so quickly!" I said, "No, I just have a very good filing system!"
I liked that once I planned the major file categories, I had quick visible results by sorting the papers into the appropriate boxes. So my mess was cleaned up right away as I was implementing the system. The system's easy to maintain as well. I also like the fact Pat Dorff's a librarian who understands the filing needs of folks like me who save paper in our many areas of interest.
One reviewer recommends Julia Morgenstern's "Organizing from the Inside Out" instead of this book for filing. I've read Julia's book twice and am in the process of implementing Julia's system for overall household organization. However, when it comes to paperwork, I much prefer Pat Dorff's system. I find Pat's system strategizes the paper problems better, is easier to implement and maintain, and is more flexible when new categories come up. Also, Pat has an extensive discussion of all sorts of filing problems, such as presorting, you can't decide how to label an item, an item is too big to fit in a file folder, etc. Finally, Pat's numerical system nicely deals with the lining up the tabs problem, while Julie's straight-line system (all tabs lined up in the same position) looks nice, but is harder to on the eye to use, and wastes the folders with center tabs.
Summary of my experience with this system: Great for filing, retrieving papers, & keeping the place neat for over a decade!
