Definition
Adjudged cases that have been reported and printed in published law books, as distinguished from records (court documents on file) and manuscript precedents in circulation. The term refers to the body of reported judicial decisions available to practitioners and scholars through printed volumes — what today would be called case reporters or law reports.
The phrase carries a descriptive rather than technical legal meaning: a "book case" is simply a decided case that exists in printed, accessible form, as opposed to an unpublished or unrecorded decision known only through private notes or court files.

Common Language
Modern common usage (Wiktionary): "Book" as a noun refers to a written or printed work bound between covers; "book case" (two words or hyphenated) commonly refers to a piece of furniture for storing books.
Historical common usage (Webster's 1913): A bookcase is defined as a case with shelves for holding books.
The gap here is complete: the legal compound term "book cases" has nothing to do with furniture. In legal usage, "book" modifies "cases" to mean cases accessible through print — the "books" being the reporters themselves. A researcher encountering "book cases" in a historical legal text should not read it as a reference to any physical container but as a shorthand for the printed case law tradition.

Common Confusion
Do not confuse "book cases" with:
**Unreported cases**: A modern unreported case is a decided case that was not selected for publication in official reporters. The historical "book case" distinction is roughly the inverse concern — whether a case had made it into print at all, in an era when printing was the exception rather than the rule.
**Precedents**: In historical usage, precedents were often manuscript forms and pleading models, not necessarily decided cases. "Book cases" specifically means adjudged (decided) cases in print, not precedents in the broader sense.

Why It Matters in Research
This term is a marker of legal culture in the era before standardized reporters and electronic databases. When historical sources contrast "book cases" with "records" or "precedents," they are drawing a meaningful evidentiary and practical distinction:
**Records** were official court documents — rolls, entries, and filings held by the court itself, carrying formal authority by their very existence as instruments of record.
**Precedents** in this context often meant manuscript copies of pleadings, forms, and practice materials circulated privately among lawyers — not yet printed, not yet standardized.
**Book cases** occupied a middle category: judicially decided, publicly available through print, and therefore citable, but their authority still dependent on the reputation of the reporter and the accuracy of the printing.
Researchers working in pre-nineteenth-century English or American legal materials should keep this taxonomy in mind. A source that says an argument is "not warranted by the book cases" is making a specific evidentiary claim — that the printed reporters do not support the proposition — not a general claim about the absence of any authority.
The distinction also matters for understanding the development of stare decisis. The authority of reported decisions was contested terrain well into the eighteenth century. Not all "book cases" carried equal weight; the reporter's identity, the edition, and whether a case was "well reported" were live questions. See the quotation from Jones, J. in 2 Show. 278, cited by Burrill, which appears in the context of distinguishing what is established by reported authority versus what exists only in manuscript or unprinted form.
For Law Mind corpus researchers: the term appears almost exclusively in older English-origin materials. It is unlikely to appear in modern American legal writing, where "reported cases," "published opinions," or simply "case law" have displaced it entirely.

Historical Dictionary Support
Burrill's Law Dictionary provides the core definition: "Adjudged cases, reported and printed in the books, as distinguished from records and precedents." Burrill attributes the usage to Jones, J. in 2 Show. 278 (Shower's King's Bench Reports, a late seventeenth-century English reporter).
The entry is brief and the surrounding text in the source material contains a fragment about "bord lands" and bordars — unrelated content that appears due to physical proximity in the original dictionary column. Researchers should not read any connection between "book cases" and manorial tenure terms; the juxtaposition is typographic, not conceptual.
No other historical dictionaries in the current source set treat this term. Its absence from later American legal dictionaries suggests it fell out of active use as standardized reporting systems became universal and the distinction between "printed" and "unprinted" authority became less practically significant.
