ERIC indexes a wide variety journal sources. The coverage of an approved journal source is determined by an examination of three to five current issues during the source review process. A journal may be switched between being comprehensively, selectively, or occasionally indexed at any time. Source coverage is defined as follows:
- Comprehensively indexed journals contain an average of 80% or more education-related articles; ERIC creates a bibliographic record for all articles in every acquired issue.
- Selectively indexed journals contain an average of 50-79% education-related articles and are critical to topic area coverage; ERIC applies a manual article-by-article selection process and indexes only the articles that conform to the standard and criteria outlined the selection policy.
- Occasionally indexed journals contain an average of 25-49% education-related articles and are determined to be critical to topic area coverage; ERIC applies a manual article-by-article selection process and indexes only the articles that conform to the standard and criteria outlined the selection policy.
The journals currently approved for indexing in ERIC are listed below.
