One easy way to keep your instruction manuals (for your digital camera, television, computer, iPod dock, blender, hand mixer, etc.) organized is to assemble a binder that can store everything.
Keep all the information for each item in a plastic sleeve. You can also keep copies of your warranties, and any repair or service receipts in there as well. Then organize the sleeves by room, and store in an easily accessible location.
Now you won't have to go on a mad scramble the next time you have a mysterious error message on your camera screen.
