I like the individual spiral binders because I can keep a dozen by my desk and they take up very little workspace and keep information separated organized and easily accessible. I use one as a notepad next to my computer to make notes during the day and then save the volumes for several months or a year so that I can go back and review as necessary thinks such as phone conversations addresses etc that I would otherwise have noted on random bits and pieces of paper. Instead of having a mess I have an organized system.
