Definition
A paper book is a printed or written compilation of the pleadings, evidence, exhibits, and procedural documents in a case, organized methodically and prepared for the use of judges when hearing an appeal or argument. The paper book presents everything the court needs to understand the matter before it without having to reconstruct the record from scattered filings — it is, in effect, a curated dossier of the case assembled for appellate review.
In English practice, paper books were prepared by the parties' solicitors and submitted ahead of argument so that judges could read themselves into the case. The term appears most frequently in older English and early American appellate practice, where oral argument was supplemented or replaced by the judges' study of the compiled record. American practice absorbed the concept but largely replaced the terminology, first with "printed record" and later with the modern "appendix" or "record on appeal."
Common Language
Modern common usage (Wiktionary): "Paper book" in ordinary English most commonly refers to a traditional printed book (hardback or paperback) as distinguished from an e-book, or a paperback book specifically.
Historical common usage: In the nineteenth century, "paper book" could refer simply to a book made of paper or a notebook — an unremarkable physical object.
The gap between common and legal meaning is meaningful in historical research contexts. A reader encountering "paper book" in a general nineteenth-century text would likely read it as a physical book; the same phrase in a law report or chancery proceeding refers specifically to the compiled appellate record. Context will usually resolve the ambiguity, but researchers working across legal and non-legal primary sources in the same period should remain alert to the distinction.
Why It Matters in Research
This term is primarily a historical research artifact. Researchers encountering "paper book" in English reports, early American appellate decisions, or nineteenth-century treatises should understand that it refers to what modern practice calls the appendix to a brief or the record on appeal — not a separate filing category with its own distinct procedural rules.
The primary trap is anachronism: a researcher familiar only with modern American appellate terminology may not immediately recognize that a court's reference to "the paper book" is simply describing the compiled record submitted for its review, rather than some independently significant document type. In English Chancery and common law court practice, paper books had a more formalized role, and historical sources from those courts should be read with that context in mind.
The term does not appear in modern American rules of appellate procedure by this name. When researching transitional periods in appellate practice — roughly the mid-nineteenth century in American courts — researchers may encounter both "paper book" and "printed record" used interchangeably, reflecting the shift from English procedural vocabulary to distinctly American conventions.
No significant corpus connections to modern practice areas. The term is most useful as a bridge concept when working in English legal history, colonial American practice, or early federal appellate records.
Historical Dictionary Support
Black's Law Dictionary defines paper book as "[i]n practice. A printed collection or abstract, in methodical order, of the pleadings, evidence, exhibits, and proceedings in a cause, or whatever else may be necessary to a full understanding of it, prepared for the use of the judges upon a hearing or argument on appeal." Black's also notes that it includes copies of proceedings on demurrer, cases, and proceedings in error — signaling that the paper book served a consolidating function across multiple procedural postures, not only straightforward appeals.
The definition is functional and accurate as far as it goes, but Black's treatment reflects the term's English origins without fully situating it within the American procedural evolution that was already underway when earlier editions were compiled. Historical sources that use this term are almost uniformly describing English practice or early American courts working in the English appellate tradition. Later editions of Black's retain the term primarily as a historical entry rather than a term of active practice.
