It can be conveniently used sitting in an armchair by the fire. Each sheet bears a number in sequence, so that the sheets cannot be used in the wrong order. Each sheet of paper presents the user with an information sequence in the form of symbols, which he absorbs optically for automatic registration on the brain. When one sheet has been assimilated a flick of the finger turns it over and further information is found on the other side. Instantly it is ready for use.
Nothing has to be connected up or switched on.
The user may turn at will to any sheet, going backwards or forwards as he pleases. A sheet is provided near the beginnning as a location finder for any required information sequence. This enables the user to pick up his programme where he left off on the previous learning session. The initial cost varies with the size and subject matter. Altogether the Built-in Orderly Organized Knowledge seems to have great advantages with no drawbacks.
