Sciences and Technology: Computers, Libraries, and the Internet

Instant information is indeed available if the owners of the information would make it so, and if the seekers were able to gain access to it (Feather, 2011, page 39). Although computers are nearly ubiquitous now, even in libraries, few people understand how they retrieve stored information, so people sometimes have difficulty retrieving information.  Feather's (2011) description below is simple, yet accurate and complete.

The computer can "make perfect matches between identical data....Once data were stored in a form which the computer could read, the machine could, for example, identify all uses of a particular word, and be programmed to show that word (perhaps in some specified context) to the operator. In this way, computers could retrieve words from ... texts, or from bibliographies, and could print the context of the former or the reference for the latter. In a different application, data on individuals could be stored, analysed and retrieved to reveal, for example, information about their spending habits or other aspects of their way of life ( p. 32).
