West Publishing began printing reporters in the late 1800s, and the collection became known as the West Reporter System. West has compiled the state appellate decisions (including intermediate appellate reports and state supreme courts) and printed them in various sets of Regional Reporters. The Regional Reporters are considered "unofficial."

- United States Supreme Court Reports, Lawyer's Edition (L. Ed. | L. Ed. 2d) - Unofficial (published by Lexis)
United States Court of Appeals:
- Federal Reporter (F. | F.2d | F.3d) - Official
- Though this reporter is published by a commercial publisher (West) it is considered an "official" reporter because there is no other comprehensive source that publishes these decisions.
United States District Courts:
- Federal Supplement (F. Supp. | F. Supp. 2d) - Official
- Though this reporter is published by a commercial publisher (West) it is considered an "official" reporter because there is no other comprehensive source that publishes these decisions.
- Federal Appendix (F. App'x) - Official
- Though this reporter is published by a commercial publisher (West) it is considered an "official" reporter because there is no other comprehensive source that publishes these decisions.
- The Federal Appendix contains "unpublished" opinions. These are decisions that do not involve new legal principles or interpretations, and because of this, were previously excluded from the official reporters (thus the term "unpublished"). Unpublished decisions issued after January 1, 2007 may now be cited by attorneys if a court so permits. However, the persuasive value will vary according to the preference of the court before which the decision is presented.
- Federal Rules Decisions (F.R.D.) - Official
- Though this reporter is published by a commercial publisher (West) it is considered an "official" reporter because there is no other comprehensive source that publishes these decisions.
- This reporter publishes cases dealing specifically with the Federal Rules of Evidence, Civil Procedure, and Criminal Procedure (three different sets of procedural rules).
