The court system has three general levels:
States have different names for the three levels, but this is the general structure.

As detailed above, the federal courts are primarily comprised of:

State and federal court cases that are chosen for official publication will eventually appear in a reporter. The most comprehensive system of state reporters is the National Reporter System published by West.

Case citations follow a standard format: volume, name of reporter, page number (court year).
Cases may be published in more than one reporter so the same text in a case will have a different pinpoint cite depending on the reporter you are reading.
Cases may be "published" or "unpublished." Published cases are those that have been certified for publication, and unpublished cases have not been certified for publication.
Only a small percentage of court opinions are published. While most, if not all, of the opinions of the federal and state supreme courts are published, less than half of intermediate appellate opinions tend to be published. State trial court opinions are never published because state trial decisions are only binding on the parties that participated in teh litigation. Only a tiny fraction of federal trial (district) court opinions are published. In this way, only a small fraction of what we think of as "cases" make it into the law books and legal databases.
Be careful: Just because an opinion makes it online into a legal database does not mean that it is a published opinion. Typically, the context of the case, such as which case reporter is reporting the case and/or introductory language identifying case as published or not, will allow you to determine whether any given case is published or not.
Most courts allow citation to published opinions only. However, there are some exceptions. When preparing a document to be submitted to a court, it is always a good idea to check the applicable court rules to confirm whether only published cases can be cited in filings with that court. Court rules may limit (or even prohibit) the citation of unpublished/unreported opinions.
Cases may be published in more than one reporter so the same text in a case will have a different pinpoint cite depending on the reporter you are reading.
The heading of a case consists of the following elements:
Case heading on Westlaw.
Case Heading on Lexis.
Case Heading in a print reporter.
The syllabus or synopsis is a summary of the case. The synopsis will provide procedural history - that is, who sued whom and for what, and who appealed - the pertinent facts, a very brief recap of the reasoning, and the holding. You should never cite a synopsis or syllabus as they are prepared by the publisher, not the court.

Headnotes summarize each significant legal issue discussed in the case opinion. Headnotes are designed to help you make a first cut analysis as to whether or not the case is relevant to your issue.
The headnote number is repeated in the main text where that issue is discussed. In this way, headnotes assist the legal researcher in navigating the opinion, by locating the part of the opinion where the relevant issue is discussed.
Headnotes on Lexis are taken verbatim from the text of the case while headnotes on Westlaw are written by attorney editors. As such, the text of the headnote in Westlaw may vary substantially from the text of the case.
Headnotes on Westlaw include a topic and a key number. West has divided the law into approximately 400 major legal topics for purposes of its digest system and arranges them alphabetically. It then divides and subdivides these topics into smaller and smaller categories that ultimately reduce to individual points of law (approximately 100,000 in total), each identified by its own “key number” (or more accurately, by its own unique topic and key number). This topic and key number system can help you find related cases.
Remember: Headnotes are editorial content and should not be cited or relied upon for legal writing purposes. Headnotes should be limited to their intended uses.
Westlaw Case Headnotes. Notice the Topic and Key Number System.
Lexis Case Headnotes.
Federal Reporter Headnotes. Notice that these headnotes match the headnotes in Westlaw - this is because this reporter, F.3d, is a West publication.
The Opinion is the part of the case that becomes primary law. A written opinion typically consists of three basic parts of primary law:
These three basic parts are all considered to be primary law and as such may be cited for authority.
A fourth part of cases, which is considered to be persuasive authority (not primary law), is “dicta.”

Lexis case opinion.
Federal Reporter case opinion.
There are four different types of appellate opinions:
There may also be partial concurrences, partial dissents, or even opinions that partially concur and partially dissent from other opinions.
Remember: concurring and dissenting opinions are not primary law; as such, they are persuasive authority.
Footnotes in the lead opinion are considered part of the official text and are often cited as precedent.
Example of the importance of footnotes: Michigan Court of Appeals Judge Gillis, in a case called Fisher v. Lowe from 1983, wrote the opinion in the form of a poem, and put the law in the footnote.
Westlaw case footnotes. These appear at the very end of the opinion.
Lexis case footnotes. These appear at the very end of the opinion.
Federal Reporter footnotes. These appear at the bottom of the page where the reference appears, rather than at the very end of the opinion.
Page numbers are necessary for pinpoint cites. Page numbers on electronic versions, known as star pagination, correspond with and match up with page numbers in printed case reporters.
Star Pagination: A symbol, historically an asterisk, indicates the page breaks for a case in different reporters.
