Traditional Methods of CAS and SDI

Current Awareness Service (CAS) and Selective Dissemination of Information (SDI) services play a crucial role in libraries, facilitating the efficient and personalized delivery of information to library patrons. CAS services are designed to keep users updated with the latest developments in their fields of interest by providing regular notifications about newly published materials, articles, and research findings. On the other hand, SDI services allow users to specify their information needs and preferences, enabling the library to disseminate relevant resources that match their criteria proactively. These services ensure that library users have access to the most up-to-date and relevant information, saving them valuable time and effort in searching for relevant materials. This article will explore the concepts and functionalities of CAS and SDI services in libraries, highlighting their significance in supporting research and academic pursuits and fostering a well-informed user community.

1.1 Traditional Methods of CAS and SDI:

Traditional methods of Current Awareness Service (CAS) and Selective Dissemination of Information (SDI) have long been employed by libraries to ensure that users stay well-informed and up-to-date in their areas of interest. Although predating the digital age, these methods continue to play a vital role in disseminating information and meeting the diverse needs of library patrons. By utilizing various communication and resource management means, libraries have successfully implemented traditional CAS and SDI practices to provide targeted information services.

• One of the fundamental methods employed is the display of newly acquired materials on library shelves or display racks. By prominently showcasing these materials, libraries create awareness and encourage users to explore the latest additions. This visual approach allows patrons to browse and discover relevant resources based on their interests. Additionally, tables of contents from newly acquired books are often posted on notice boards strategically placed within the library. This practice enables users to quickly assess the content of these books and determine their relevance to their research or study areas.
• Newspaper cuttings also play a significant role in traditional CAS and SDI services. Libraries collect and organize these cuttings, archiving them in albums or files. Researchers and library users can access this valuable resource to keep abreast of current information and developments within their fields of interest. The compilation of bibliographies, reading lists, and indexes further enhances the dissemination of information. Libraries meticulously curate and create comprehensive lists of recommended readings and resources, allowing users to easily locate materials on specific topics.
• Collaboration with department heads is another integral part of traditional CAS and SDI services. Libraries communicate with the leaders of various academic departments, notifying them about new materials acquired that may benefit their respective courses of study. This proactive approach ensures faculty members are informed about relevant resources and can incorporate them into their teaching and research activities. Such collaboration strengthens the partnership between libraries and academic departments, fostering a more efficient and productive learning environment.
• Publishers also contribute to CAS and SDI by engaging in practices such as producing catalogues showcasing their latest publications. These catalogues, whether general or subject-specific, are distributed to libraries and academic departments. They serve as valuable resources, informing users about new releases and enabling them to explore publications from different publishers. Moreover, libraries prepare and display bibliographies in various subject areas, providing users with curated lists of recommended readings and research materials.

While traditional methods of CAS and SDI have charm and historical significance, they have evolved alongside digital advancements. Libraries now incorporate modern technologies and digital platforms to complement and enhance these traditional practices. Online catalogues, email notifications, and electronic databases have expanded the reach and accessibility of CAS and SDI services, ensuring users can access information regardless of physical location.

In Summary, traditional methods of CAS and SSDI in libraries have proven to be effective means of disseminating information and meeting the diverse needs of library patrons. Through displaying newly acquired materials, posting tables of contents, organizing newspaper cuttings, collaborating with department heads, compiling bibliographies, and partnering with publishers, libraries have created a rich environment for users to stay informed and engaged. As libraries continue to evolve in the digital age, these traditional methods are being complemented by innovative technologies, ensuring that CAS and SDI services remain effective and relevant in catering to the evolving information needs of library users.
