User-needs studies often present figures indicating that documentation services systems which rely on the mails are inherently incapable of effectively supporting more than half of all research and development tasks. In addition to investigating faster ways of transmitting information, DDC has also been developing and testing systems based on another approach one of determining users specific documentation requirements and automatically disseminating the needed documentation to the users local libraries as soon as it becomes available. This general concept was applied to the selective dissemination of both report announcements and full-text reports. Three different types of selective announcements, all produced on a regular semimonthly basis, were developed and tested 1 automatic bibliographies, 2 group announcement bulletins each of which contained announcements in just one of the 188 specific DoD-modified COSATI subject categories, and 3 selected announcements on magnetic tapes which could then be used as a basis for local SDI services. Selected reports were disseminated on the same semimonthly basis as the announcements, but in only one form--microfiche.
