Selective Dissemination of Information definition library
(SDI) (From Library Science) SDI is a current awareness system which alerts you to the latest publications in your specified field(s) of interest.
A user registers at such a system with keywords representing his or her fields of interest, called a search profile. When new publications matching the search profile appear, the system informs the user of them instantly, periodically or upon request. Some systems may also be able to inform the user if changes in already notified publications occur.
