Description: This article discusses artificial intelligence, libraries, and information retrieval. In the science fiction short story "Anniversary" (Amazing, March 1959), Isaac Asimov described a computer system that combined advanced elements of artificial intelligence and information retrieval. Called "Multivac" in the story (The author wonders if the name was inspired by the UNIVAC systems that were being marketed in the early fifties), Asimov's system is described as "a mile-long super-computer that was the repository of all the facts known to man; that guided man's economy; directed his scientific research; helped make his political decisions--and had millions of circuits left over to answer individual questions that did not violate the ethics of privacy." Multivac was capable of understanding and answering what we would now call natural language queries on any topic. The protagonists of the story typed in their questions on a terminal that worked much like a typewriter.

Description: This article discusses copyright, digital media, and libraries. Librarians are ostensibly supposed to be experts on the proper use of the collections of information they administer. This column is devoted to a brief bibliography on the subject of copyright and digital media. The author had never considered many of the issues raised in the sources reviewed below and thinks they will be of interest to all librarians who have added any kind of digital media (e.g., software and CD-ROM databases) to their collections.

Description: This article discusses Public-Access Computer Systems (PACS) and the Internet. Recursive Reviews is a new column that will identify and briefly describe articles that deal with PACS and related topics in both library and computer science literature. The "recursive" in the name of the column emphasizes the idea that the discussion of information technology in libraries changes the underlying precepts of the discussion. The dialogue concerning uses of library technology redefines itself in this way, and can therefore be seen as recursive. All followers of the PACS-L forum are aware by now that a great many library catalog systems are accessible via the Internet. The availability of these resources raises a great many questions and possibilities in the library and network user communities. What can be accomplished with this new communications channel? Exactly what is the Internet? What is its extent, and how does it differ from other computer networks? The articles and books reviewed in this column will be of use to anyone having questions about library systems and the Internet, from those unfamiliar with networking technology to those very conversant with it.
