The only issue then becomes how much information you need to keep and where and in what equipment you need to keep it in order to have it accessible when you want it. Nothing's perfect in that regard, but as the small digital tools become easier to use and connect to larger databases, you'll be able to have more information at hand with the same or less effort.
If material is purely for reference, the only issue is whether it's worth the time and space required to keep it.
Some degree of consistency will always make things easier. What kinds of things do you need with you all the time? Those must go into your ubiquitous planner or PDA. What do you need specifically for meetings or off-site events? That should be put into your briefcase, pack, satchel, or purse. What might you need when you're working in your office? That should be put into your personal filing system or your networked computer. What about rare situations relative to your job? Material needed for those could be archived in departmental files or off-site storage. What could you find anytime you might need it, on the Web? You don't need to do anything with that information, unless you need it when you're away from a Web connection, in which case you should print the data out when you're online and store it in a file you can take with you.
Do you see how that personal organization of reference material is simply a logistical issue? Distinguishing actionable things from nonactionable ones is the key success factor in this arena. Once you've done that, you have total freedom to manage and organize as much or as little reference material as you want. It's a highly individual decision that ought to be based on the ratio of the value received to the time and effort required to capture and maintain it.
Someday/Maybes
The last thing to deal with in your organization system is how to track things that you may want to reassess in the future. These could range from a special trip you might want to take one day, to books you might want to read, to projects you might want to tackle in the next fiscal year, to skills and talents you might want to develop. For a full implementation of this model you'll need some sort of "back burner" or "on hold" component.
Someday/Maybe's are not throwaway items. They may be some of the most interesting and creative things you'll ever get involved with.
There are several ways to stage things for later review, all of which will work to get them off your current radar and your mind. You can put the items on various versions of "Someday/Maybe" lists or trigger them on your calendar or in a paper-based "tickler" system.
"Someday/Maybe" List
It's highly likely that if you did a complete mind-sweep when you were collecting things out of your psychic RAM, you came up with some things you're not
If you haven't already done it, I recommend that you create a "Someday/Maybe" list in whatever organizing system you've chosen. Then give yourself permission to populate that list with all the items of that type that have occurred to you so far. You'll probably discover that simply having the list and starting to fill it out will cause you to come up with all kinds of creative ideas.
