Exceptions for Edition (required) for Journal Articles Vancouver Style

After NLM establishes an abbreviation for a title with an edition, the abbreviation usually stays that way in MEDLINE/PubMed, even if the rules change. You may see contradictory abbreviations for some titles with editions; for example:

Archives of Disease in Childhood. Fetal and Neonatal Edition. was established as

Arch Dis Child Fetal Neonatal Ed

not

Arch Dis Child (Fetal Neonatal Ed)

but

British Medical Journal. Clinical Research Edition. was established as Br Med J (Clin Res Ed)
