Chapter 2: Locating information

2.8 Articles and databases

Quick Search is the best place to start your research if books or book chapters are what you need. Quick Search can help find some articles; however, if you find you need more results or highly specialized articles, the library has other tools that may be more effective.

When you need to find a comprehensive set of articles on your topic, the most efficient finding tool to use is an article index. In the context of scholarly research, an index is an article finding tool, rather than a list of topics and page numbers in the back of a book. Article indexes (sometimes referred to as databases) help you identify and find articles on your topic. An article index allows you to search for your topic in hundreds of journals at once, so using an index is a huge time saver when you don’t have one specific journal in mind. Some indexes also cover magazines, newspapers, book chapters, conference presentations, dissertations, or other materials.

Which index should you choose?

The ISU Library subscribes to hundreds of article indexes providing access to articles. Each index is different in terms of:

  • subject(s) covered
  • types of materials included
  • whether materials are peer-reviewed
  • whether abstracts (brief summaries of content) or full-text materials are provided
  • dates included
  • languages included
  • overall design and search options

Features of article indexes

Indexes provide a variety of robust advanced search features to help researchers focus their searches. You can typically select, sort, and download articles or article abstracts. For scholarly research, indexes tend to be either general purpose or subject-focused.
