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.
