Minicomputers are both technically suitable and cost effective for information storage and retrieval systems. Soft ware packages for structured database management and for free text systems are well established and can reduce both the costs and the technical difficulties of setting up an informa tion management system. The particular requirements of designing minicomputer systems are described, and some practical consequences indicated. A number of commercially available free text systems are listed with their salient fea tures. It is expected that free text systems rather than struc tured databases will prove to be of most use to the informa tion scientist or librarian.

Theory Of Information

In the paper is developed a theory of information storage and retrieval systems which arise in situations when a whole possessed information amounts to a fact that a given document has some feature from properly chosen set. Such systems are described as suitable maps from descriptor algebras into sets of subsets of sets of documents. Since descriptor algebras turn out to be pseudo-Boolean algebras, hence an “inner logic” of our systems is intuitionistic. In the paper is given a construction of systems and are considered theirs properties. We will show also (in Part II) a formalized theory of such systems.
