Purpose -This paper aims to explore the effective ways to utilize current awareness services (CAS) for library and information science (LIS) professionals. It seeks to identify core journals for systems librarianship based on Bradford analysis. Design/methodology/approach -The study explored the methods for CAS based on literature review, followed by Bradford analysis of systems librarianship literature, which was conducted by the quantitative analysis approach. Findings -A core journal list for systems librarianship was built based on Bradford analysis. Three effective ways to utilize CAS by table of contents (TOCs) alerts were identified. Originality/value -To keep up to date with the latest literature in the field of interest, LIS professionals should take advantage of CAS. The study found three effective ways to utilize CAS by TOCs alerts and identified core journals for systems librarianship. The research can help LIS professionals efficiently navigate the information tsunami to obtain the reliable and relevant information that deserves their time and attention, and stay aware of new developments in their area of interest.
