Abstract
An information search system, includes a storage device in which, for example, words are alphabetically arranged, each word being coded by a number for each letter or character and a number corresponding to the order of each letter in the word. The letter code numbers of a word to be searched are successively fed into an input station whose output actuates a counter for a unit and is also coded into a corresponding letter number. Two pickups and associated registers read out and temporarily store the order number and letter number respectively and feed them to respective comparator networks to which are also fed the counter and encoder output respectively. Control networks are provided which respond to the comparator network outputs such that when the read out order number is greater or less than the counter output number the storage device is driven in a reverse or advance direction respectively and when the counter and order numbers are equal the order comparator network is actuated to drive the storage device in advance or return directions in accordance with the relationship of the read out and input letter codes until these numbers are equal.
