The National Conference of State Legislatures has a legislative tracking database.
Subject Compilations of State Laws: Database that allows you to search and browse for articles, bibliographies and websites that have compiled state laws by subject. Virginia Tech has a short guide for how to use the database here.
American Law Reports (A.L.R.) can be useful for obtaining an overview of the law on a specific topic and for locating citations to cases, both within the jurisdiction and in other states. References to A.L.R. annotations are often found in secondary sources, code annotations, and citators. Available in print and on Westlaw and LexisNexis.
