Statutory laws are the laws created by federal and state legislators. When a legislative body (e.g. the U.S. Congress or the Ohio Legislature) passes a bill, it becomes a statute after the executive signs it into law.
The U.S. Code is a topical arrangement of all of the federal laws currently in force.
All states also publish chronological public laws and codified laws. In Ohio, the topical arrangement of laws is called the Ohio Revised Code.
There are several websites below that will help you find bills and laws for specific states. This is not an exhaustive list of resources, but a starting point for your research.
Sometimes these websites include legislative documents, hearings, committee reports, and analyses.
You can also find the annotated revised codes for specific states in LexisNexis, which will include statutory history for specific sections of the code.
