Discuss the detail the Selective Dissemination of Information Service (SDI). Also write whether it is CAS service or not.

 Selective Dissemination of Information (SDI) service is a type of information service that aims to provide users with information that is relevant to their specific needs and interests. The service typically involves the user providing the SDI provider with information about their research interests and fields of expertise. The provider then uses this information to identify and deliver relevant information to the user, such as articles from journals, conference proceedings, and other documents.


The process of SDI typically involves the following steps:

  1. User registration: The user provides the SDI provider with information about their research interests and fields of expertise.
  2. Profile creation: The SDI provider uses the information provided by the user to create a profile that summarizes the user's research interests.
  3. Information monitoring: The SDI provider monitors a variety of sources, such as journals, conference proceedings, and online databases, to identify information that is relevant to the user's profile.
  4. Information selection: The SDI provider selects the most relevant information and delivers it to the user.
  5. User feedback: The user can provide feedback on the relevance of the information received and make suggestions for future searches.


SDI service can be automated using software such as CAS (Current Awareness Service) that continuously monitors multiple databases, and based on the user's profile, it sends the new and relevant information to the user.

In conclusion, Selective Dissemination of Information (SDI) service is a type of information service that aims to provide users with information that is relevant to their specific needs and interests. It involves a process of user registration, profile creation, information monitoring, information selection and user feedback. It can be automated using CAS (Current Awareness Service) which is a software that continuously monitors multiple databases, and based on the user's profile, it sends the new and relevant information to the user.
