The role of a periodical index for researchers primarily revolves around its ability to help them find articles about specific topics, organized by subject or author. A periodical index serves as a comprehensive tool that lists articles from various periodicals, making it easier for researchers to locate relevant literature in their field of study. By indexing articles based on keywords, authors, and subjects, it allows researchers to quickly narrow down their search to find pertinent information related to their research questions or interests.

In contrast, a periodical index does not serve as a complete catalog of all published works, nor does it provide direct access to articles on request. Researchers still require libraries or online databases to access full articles. Additionally, while online databases have become essential in modern research, a periodical index does not eliminate the need for them; instead, it complements these resources by providing a systematic way to identify and locate content.
