In civil law jurisdictions, codification has also occurred in many areas.

In the United States acts of Congress (i.e., Federal statutes) are published chronologically (that is, in the order in which they become law -- often by being signed by the President) on an individual basis in official pamphlets called "slip laws," and are grouped together in official bound book form (also chronologically) as "session laws." The "session law" publication for Federal statutes is called the United States Statutes at Large. Any given act may be only one page long, or hundreds of pages, in length. An act may be classified as either a "Public Law" or a "Private Law." The United States Statutes at Large, commonly referred to as the Statutes at Large, is the official source for the laws and resolutions passed by Congress. ...

Because each Congressional act may contain laws on a variety of topics, many acts (or portions thereof) are also rearranged and published in a topical, subject matter codification. The official codification of Federal statutes is called the United States Code. Generally, only "Public Laws" are codified. The United States Code is divided into "titles" (based on overall topics) numbered 1 through 50. Title 18, for example, contains many of the Federal criminal statutes. Title 26 is the Internal Revenue Code. The United States Code (U.S.C.) is a compilation and codification of the general and permanent federal Law of the United States. ...

Even in code form, however, many statutes by their nature pertain to more than one topic. For example, the statute making tax evasion (see Tax avoidance/evasion) a felony pertains to both criminal law and tax law, but is found only in the Internal Revenue Code. Other statutes pertaining to taxation are found not in the Internal Revenue Code but instead in (for example) the Bankruptcy Code (i.e., Title 11 of the United States Code) or the Judiciary Code (Title 28). This article contrasts tax avoidance, tax evasion, tax mitigation, tax fraud, tax resistance and tax protesters. ...

Further, portions of some Congressional acts (such as the provisions for the effective dates of amendments to codified laws) are not themselves codified at all. These statutes may by found by referring to the acts as published in "slip law" and "session law" form. However, commercial publications that specialize in legal materials often arrange and print the uncodified statutes with the codes to which they pertain.

In the United States, the individual states (either officially or through private commercial publishers) generally follow the same three-part model for the publication of their own statutes: slip law, session law, and codification.
