The rate of new technology-driven innovations for information delivery has accelerated over the past three decades. New information delivery formats in the 1950s and 1960s included microforms and, in response to demands from librarians, indexing and abstracting services began to make their publications available on this medium. Electronic processing and delivery of machine-readable records became a reality in the late 1960s; magnetic tapes were developed, and online distribution followed. Online usage on a broad scale occurred much more quickly than predicted, first as bibliographic entries, then as abstracts, and finally full-text formats became available online. Recent information delivery mechanisms and issues include floppy discs, downloading, vertical integration, value added, electronic publishing, optical discs, and CD-ROM. These technological applications have had a vast impact not only on the way information is processed and delivered to its point of use, but also on how it is used. During the decade ahead, the need for carefully weighed decisions will be greater than ever. Material pertinent to this topic is listed in an accompanying 34-item bibliography. (Author/KM)
