Current Awareness Service (CAS) is a service that provides users with information about new publications in their field of interest. This information can be delivered in various formats, such as a weekly newsletter, a daily email alert, or a custom-designed dashboard. Libraries, research institutions, and commercial vendors can provide CAS services. Difference between SDI and CAS
Selective Dissemination of Information (SDI) is a type of CAS service tailored to an individual user’s specific needs. SDI services typically use a computer to track new publications and deliver only those relevant to the user’s interests. This can save users significant time and effort, as they do not have to search for new information manually.
The main difference between CAS and SDI is the level of personalization. CAS services provide a general overview of new publications, while SDI services deliver only the most relevant information to the user. This makes SDI services more efficient and effective for users with specific information needs.
Selective Dissemination of Information VS Current Awareness Service
| Feature | SDI | CAS |
|---|---|---|
| Focus | SDI is a service that focuses on providing individual users with information that matches their specific interests and needs. |
On the other hand, CAS is a service that provides users with information on the latest developments in a particular field of interest. |
| Scope | SDI is typically a more comprehensive service than CAS, as it covers a wide range of sources and types of information. | Conversely, CAS may be limited to a specific set of sources or types of information. |
| Purpose | To keep users informed of new publications in their field of interest. | To provide users with the most relevant information about new publications. |
| Personalization | SDI is a highly personalized service, as it is tailored to each user’s individual needs and interests. | CAS, while still customizable to some extent, is generally less personalized. |
| Delivery | SDI typically delivers information to users regularly through email, RSS feeds, or other means. | CAS, on the other hand, may deliver information in real-time or on a less frequent basis. |
| Automation | SDI is a highly automated service relying on algorithms and search technologies to match information to user profiles. | CAS may also somewhat use automation but is more likely to rely on human editors to curate information. |
| Level of customization | SDI is highly customized to the individual user’s specific interests and needs. | CAS provides more general information that may be relevant to a larger group of users. |
| Timing | SDI is a proactive service that delivers information to the user regularly. | CAS is a reactive service that requires users to seek information regularly and actively. |
Which service is right for you?
A CAS service may be a good option if you are looking for a general overview of new publications in your field of interest. CAS services are typically free or low-cost and can be provided by various organizations.
An SDI service may be better if you have specific information needs. SDI services are more expensive than CAS services but can save time and effort.
Ultimately, the best way to decide which service is exemplary for you is to consider your needs and preferences.

Hi,
May I know if is there any commercial platform/software for SDI where it can be used to sort the data/publication before it can be sent to the users?
I am looking for a platform in which SDI can be conducted automatically.
Thank you.
