Book Structure

  • Part 1 - Bluepages - a how-to guide for basic legal citation
  • Part 2 - heart of citation system consisting of 2 sections
    • Rules 1-9, establishes general standards of citation & style
    • Rules 10-21, presents rules for citation of specific types of authority
  • Part 3 - Series of tables to be used in conjunction with the rules.
Things to Keep in Mind
  • Many courts have their own rules of citation that may differ from The Bluebook. Check requirements before submitting documents.
  • Typeface
    • Tradition of underscoring maintained; Italics  may be substituted for underscoring in Bluepages.
    • Refer to Bluepages B2 (page 6) for additional Typeface conventions
  • Use the Whitepages when Bluepages or local court rules citation format is not detailed. 
  • Elements of a Citation
    • A signal
    • The source of authority
    • Parenthetical information
Structure (B1, pg. 4)

Briefs & Opinions (Non-academic legal documents)

  • Citations generally appear in document text immediately following the propositions they support. 
  • Footnotes should only be used when permitted/required by local court rules

Citation Sentences

  • Begin with capital letter and end with a period. 
  • A sentence may contain multiple citations separated by semicolons. 
  • Used to cite sources/authorities related to entire preceding sentence

Citation Clause

  • Set off from text by commas and immediately follow the proposition to which it relates.
  • Does not begin with a capital letter unless it begins with title of a source that should be capitalized.
  • Do not end with a period unless it is last clause in a sentence
  • Used to cite sources/authorities related to a part of a sentence
Signals (B1.2, pg 4-5)

Signal - shorthand message to the reader about relationship between proposition and the source/authority cited

Signal Use
[no signal]

Authority directly states a proposition, is the source of a quotation or was mentioned in the proposition

E.g., Authority is one of multiple authorities directly stating same proposition. 
Accord Multiple authorities directly stating or supporting the proposition, and another authority was mentioned in proposition. 
See Authority supports, but does not directly state proposition
See Also Authority provides additional materials supporting the proposition
Cf. Authority is different from the main proposition but sufficiently analogous to lend support
Compare . . . [and] . . . with . . . [and] . . .

Authorities are similar or different in important respects

Contra Authority directly states a proposition contrary to main proposition
But see Authority clearly supports a proposition contrary to the main proposition
But cf. Authority supports a proposition analogous to the contrary of the main proposition
See generally Authority is helpful background material related to the proposition

*** Refer to rule 1.3 for the grouping & ordering of signals
*** Refer to rule 1.4 for guidance on the order of authorities

Parentheticals (B1.3, pg. 5)

Subdivisions (B3, pg. 7)
