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 the online publication, currently available on Lexis Advance.
Similarly, when you see West by itself in a parenthetical it always means a print publication. West, Westlaw means traditional Westlaw.com the current online product.
Example from T1, Hawaii:
Table 1 shows you how to format a citation to Hawaii Revised Statutes. 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
