Citations are to the 20th edition of The Bluebook, A Uniform System of Citation.
In Bluebook parentheticals the term LexisNexis is different from LEXIS or Lexis Advance. LexisNexis always refers to a print publication while the other two are electronic. LEXIS means lexis.com or traditional LEXIS. Lexis Advance is the current incarnation of lexis.com.
Similarly, when you see West in a parenthetical it always means a print publication. Westlaw means traditional Westlaw.com and Westlaw is the current product. (Westlaw will disappear in July of this year.)
Example from T1, Hawaii:
Table 1 shows you how to format a citation to the administrative compilation. But the citation shown, like many of the formats shown in Table 1, is to the print publication. Therefore, it is a pattern to follow. You have to change the parenthetical to reflect the resource you actually used just in case there is a difference. So the possible parentheticals are
Haw. Code R. § 12-46-306 (LexisNexis <year in print pub.>);
Haw. Code R. § 12-46-306 (Lexis Advance <year at the top of the document on Lexis Advance>).
Haw. Code R. § 12-46-306 (Westlaw <year from currentness statement linked at the top of the document on Westlaw>).
