ABSTRACT:
In an electronic computer, an arrangement for retrieving by means of search key words, information records on a record carrier having index key words associated with the records. The search key word is compared in succession with the index key words for identifying the position of the index key word on the carrier. The position of the index key word on the carrier enables the identification of the location of the record associated with the search keyword. The location so identified is used for accessing the information record associated with the search key word.
