Why are some article titles enclosed in square brackets [ ] in PubMed?
Answer
When an article title is enclosed in square brackets [ ], it is an indication that the article is in a non-English language. In most instances, the PubMed citation indicates the language in which the article is available. When requesting a non-English article through ILLiad, put "will accept non-English" in the Notes section of the request form, or your request may be cancelled.
