If a researcher is not familiar with federal civil procedure, including the Federal Rules of Civil Procedure, it is helpful to consult secondary sources. Note: A practitioner is more likely to use a comprehensive multi-volume treatise (examples: Federal Practice and Procedure, available in Westlaw and Moore's Federal Practice, available in Lexis). These multi-volume treatises are highly useful when one seeks an in-depth discussion of a particular rule and wants to find cases interpreting the rule.
