A restatement published in several subtitled volumes keeps its subtitle in the citation title, since the volume a section comes from cannot otherwise be told from the title alone.¹

1. 1R. 12.9.4 Model Codes, Principles, Restatements, Standards, Sentencing Guidelines, and Uniform Acts.
2. 2A warning: the form is usually wrong under the rule in note 1, and context can justify it.
