Introduction

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
analogous systems for SDI services include alerts, current awareness tools or trackers. These systems
provide automated searches that inform the user of the availability of new resources meeting the
user’s specified keywords and search parameters. Alerts can be received a number of ways, including
e-mail, RSS feeds, voice mail, Instant messaging, and text messaging.
