Abridged index medicus differs from index medicus in that it

• A. Contains broader coverage including non-English
• B. Is more current
• C. Contains citations to English-language journal only
• D. Is less selective

Answer: (C)

The key idea is the scope of language covered. Abridged Index Medicus is a shortened version of the full Index Medicus that restricts its citations to English-language journals only. This makes it narrower in coverage than the complete Index Medicus, which includes journals in multiple languages. So the correct distinction is that it contains citations to English-language journals only. The other statements don’t fit because abridged Index Medicus does not expand coverage to non-English sources, isn’t inherently more current than the full index, and is more, not less, selective by narrowing language scope.
