Once a law is signed by the Governor, it is printed as an individual "slip law" and assigned a chronological chapter number. These chapters are reprinted in the General and Special Laws of Texas, also call the "Session Laws", which is published at the end of the legislative session. Each session law includes the official chapter number (used for citing the bill), the bill number, a subject-based caption, the section of Vernon's that the law amends, the text of the law, a vote tally, date of the governor's signature, and the effective date. The law is then codified by subject into Vernon's Texas Statutes and Codes Annotated, which, although privately published, is the official codification for Texas law. An online version of both the Vernon's Statutes and enrolled bills from the last three legislatures is available from the Texas Legislature Online.
To find laws by subject, begin with either the Texas Code from LexisNexis or the Texas Statutes database from the Texas Legislature Online. Otherwise, the best place to begin is with the cumulative indexes to Vernon's Texas Statutes and Codes Annotated.
