Selective dissemination of information ("SDI") was originally a phrase related to library and information science. SDI refers to tools and resources used to keep a user informed of new resources on specified topics.
SDI services pre-date the world wide web, and the term itself is somewhat dated. Contemporary terms for SDI services include alerts, current awareness tools or trackers. These systems provide automated searches that inform the user of the availablilty of new resources meeting the user's specified keywords and search parameters. Alerts can be received a number of ways, including email, RSS feeds, voice mail, Instant messaging, and text messaging.
