Cases are published electronically and in print in volumes called court reports or case reporters.
The text of an opinion should be identical in both the official and unofficial reporter. The only difference between an official and an unofficial reporter is under whose authority the reporter is published. The confusion between official and unofficial reporters may be caused by the fact that the federal government and many states have chosen to have a commercial publisher, Thomson Reuters, to publish the official court reporters for their jurisdiction. Thus, the South Eastern Reporter is the official reporter for the state of West Virginia but the unofficial reporter for the state of Virginia.
As law students, follow the Bluebook rules along with any specific guidance from your professor.
For each state, Table T1 (page 227) lists the case reporter you should cite along with its correct abbreviation.
Cases are often published in more than one case reporter. When a case citation includes cites to the same case published in multiple reporters, that is known as a parallel citation. Bluebook Rule 10.3.1(a) (page 103) requires that if a document is being filed in state court and the state court rules require a parallel citation then a parallel citation must be used. It is important to note that both requirements must be met. A parallel citation is never correctly used in an ordinary legal memoranda.
Some cases are not designated for publication by the courts.
"Some courts and legislatures have attempted to control the publication of judicial opinions by limiting publication to those opinions that (1) enunciate a new rule of law or change or modify an existing rule; (2) apply an established rule of law to a new or significantly different fact situation; (3) involve a legal issue of continuing public interest; (4) criticize existing law; (5) resolve an apparent conflict of authority; or (6) contribute to the legal literature by collecting relevant case law or reciting legislative history."

Unpublished cases can be found in various places:
Use of unpublished cases on the state level is governed by court rules. States differ in allowing citation to use cases. On the federal level, the use of unpublished cases has been allowed since 2007. See Rule 10.8.1 (page 112) for information on pending and unreported cases.
