Comparing state laws is a fairly common research task, and arises in a wide variety of contexts. Before looking for individual state statutes, find out if the comparison you’re interested in has already been done.
The tab, Multiple Subject Sources, describes topical finding aids for surveys of state laws available in the Chastek Library (both print and online). Resources that survey legislation on specific topics are listed alphabetically by subject under the Subject-Specific Sources tab.
Keep in mind that legislation changes frequently, so review each statute for currency.
