ISC Core Collection is a repository of the journals with the highest caliber in various disciplines and subject areas. The journals undergo rigorous content analysis by a panel of experts in the relevant disciplines based on a set of stringent criteria to ensure the high quality of the scientific content. The novelty of research topics, applicability of research findings in the field, readability, academic quality, sound methodology, clear and systematic presentation of the findings, logical discussion, sound reasoning, and deductions are some of the metrics considered while evaluating the titles for coverage in the core collection. The journals covered in the core collection undergo periodic annual evaluation, and once they fail to meet the inclusion criteria, they are relegated to either the ISC waiting list or the ISC primary journal list depending on the degree of backslide.
