Definition
Commercial paper refers to negotiable instruments for the payment of money that arise in the ordinary course of business. The term encompasses bills of exchange, promissory notes, bank checks, and similar written instruments that, by their form and on their face, are recognized under the law merchant as negotiable. Two distinct uses of the term require careful attention:
1. Traditional / Law-Merchant Sense: Any negotiable instrument — promissory note, bill of exchange, draft, or check — created by a merchant, banker, or trader in the due course of business. This is the sense that dominates historical legal dictionaries and most pre-UCC case law.
2. Modern Finance / Securities Sense: Short-term, unsecured debt instruments issued by corporations to raise working capital, typically with maturities of 270 days or fewer. This is the sense most common in contemporary financial regulation, particularly under the Securities Act of 1933 (where short-term commercial paper is generally exempt from registration requirements) and in money market contexts.
The distinction matters: a researcher encountering "commercial paper" in a nineteenth-century court opinion is almost certainly reading about negotiable instruments law, not corporate debt markets.

Common Language
Modern common usage (Wiktionary): A negotiable instrument with short maturity.
Historical common usage (Webster's 1913): Webster's 1913 does not carry a standalone entry for "commercial paper" as a term of art, treating it as a descriptive phrase for paper used in commerce — broadly, any written instrument passing in trade.
The gap between common and legal usage has widened over time in opposite directions. Ordinary modern usage (and financial journalism) has narrowed "commercial paper" almost entirely to the corporate short-term debt meaning — the kind issued by large firms in the money markets. Legal usage, especially in older sources, is considerably broader, covering the full range of negotiable instruments. A researcher who assumes the narrow modern sense when reading historical legal sources will systematically misread those materials.

Common Confusion
Commercial paper is frequently conflated with two adjacent concepts:
NEGOTIABLE INSTRUMENT: All commercial paper (in the traditional sense) is negotiable instrument, but not all negotiable instruments are commercial paper. The latter term historically carried the additional requirement that the instrument arise in the due course of business — a promissory note given purely for personal reasons might be a negotiable instrument without qualifying as commercial paper in the law-merchant sense.
CHATTEL PAPER: Under Article 9 of the Uniform Commercial Code, "chattel paper" is a distinct category of collateral — a record evidencing both a monetary obligation and a security interest in specific goods. Researchers working in secured transactions must not confuse chattel paper with commercial paper; the UCC treats them as separate collateral classifications with different attachment, perfection, and priority rules. See the Encyclopedia entry on Classification of Collateral.

Recognized Forms
/ SUBTYPES
1. Bills of Exchange (Drafts): Written orders directing a third party to pay a specified sum to the holder.
2. Promissory Notes: Written promises by the maker to pay a specified sum to the payee or order.
3. Bank Checks: Drafts drawn on a bank, payable on demand.
4. Corporate Commercial Paper (Modern): Unsecured short-term obligations issued by corporations, often sold at a discount and redeemed at face value upon maturity.

Why It Matters in Research
The term is a navigational hazard precisely because it looks stable when it is not. Researchers should attend to three persistent traps:
First, temporal displacement. Pre-UCC cases and treatises use "commercial paper" to mean the full landscape of negotiable instruments. Post-UCC scholarship increasingly reserves the phrase for short-term corporate debt. An opinion from 1890 calling a promissory note "commercial paper" is not speaking anachronistically — it is using the term correctly for its era.
Second, the due-course-of-business requirement. Historical sources (Bouvier especially) consistently insist that commercial paper is paper given "in the due course of business" by a merchant, banker, or trader. This qualification had legal teeth: it affected holder-in-due-course analysis and certain defenses available to makers. Instruments of a purely private character were sometimes excluded from the commercial paper classification even if formally negotiable.
Third, corpus connections to secured transactions. Modern researchers working in UCC Article 3 (Negotiable Instruments) and Article 9 (Secured Transactions) will find the term operating differently in each. Article 3 governs the instrument itself; Article 9 classifies instruments as a category of personal property collateral. Understanding which body of law governs the research question determines which secondary literature and which dictionary sense applies.
Researchers tracing the law-merchant tradition will find Rapalje & Lawrence's cross-references to BILL OF EXCHANGE and NEGOTIABLE the most useful starting points in the historical shelf. Bouvier's note that negotiability may derive from "the law merchant or by statute" is significant — it signals that state negotiable instruments statutes (pre-dating the UCC) were already expanding the category beyond pure common-law commercial paper.

Historical Dictionary Support
The three shelf dictionaries converge on the core definition: commercial paper is negotiable paper for the payment of money, arising in the due course of business. Black's and Bouvier's are in near-complete agreement on this formulation, both drawing on the same cluster of federal circuit authorities (the 5 Biss. citations in Bouvier refer to reported decisions of the U.S. Circuit Court for the Northern District of Illinois, a significant commercial center in the post-Civil War period).
Where the sources diverge is in emphasis. Black's stresses the form-and-face test — whether the instrument, on its face, presents itself as the kind of paper recognized by the law merchant. Bouvier's adds the statutory dimension, noting explicitly that negotiability may be conferred by statute rather than common law alone, which anticipates the trajectory toward codification in the Uniform Negotiable Instruments Law (1896) and eventually the UCC.
Rapalje & Lawrence does not provide a substantive definition, functioning instead as a finding aid with cross-references to BILL OF EXCHANGE, NEGOTIABLE, and PROMISSORY NOTE. This cross-reference structure is itself informative: it tells the researcher that in the late nineteenth century, "commercial paper" was understood as an umbrella category, with its operative content distributed across those sub-entries.
What historical dictionaries collectively miss is any anticipation of the modern money-market sense. None of the shelf sources contemplates large-scale corporate issuance of standardized short-term obligations as a distinct instrument class. Researchers should not project that modern meaning backward.

Jurisdictional Note
Prior to uniform codification, the law of commercial paper varied meaningfully by state, particularly regarding what instruments qualified as negotiable and what defenses were available against holders. The adoption of the Uniform Negotiable Instruments Law beginning in the 1890s and then the UCC beginning in the 1950s substantially harmonized domestic law, though state-level enactments and official comments still produce variation at the margins. Internationally, bills of exchange law continues to diverge significantly between common-law and civil-law jurisdictions.
