Westlaw and LexisNexis Citations Aren't Bluebooked

One mistake students and attorneys alike make is assuming that research systems like WestlawNext and Lexis Advance provide properly Bluebooked citations. This is usually incorrect, but the citations these services produce look pretty good. Be sure to verify the components of a proper citation, especially the abbreviation.  A citation copied directly from WestlawNext, in particular, is easy to identify, because the source name will be an abbreviation, but not one approved by the Bluebook.

Cases

  1. Forgetting to put a court designation in the court and date parenthetical when the reporter information is not sufficient.
  2. Guessing on the abbreviations in case names instead of checking Table 6.
  3. Omitting the volume and reporter information in a case short form.
  4. Omitting the comma between the case name and the volume information in a case short form.
  5. Omitting the space between "F." and "Supp." for cases reported in the Federal Supplement.
  6. Omitting the space between "Supp." and "2d" for cases reported in the Federal Supplement, Second Series.

Statutes

  1. Omitting the date or currency statement in the parenthetical for a citation to a statute found on WestlawNext or Lexis Advance.
