With this, and any other topic, remember that not only can you find sources online, you can also find Research Guides which will give you additional assistance in locating materials. For example, if you Google "researching state law," you'll locate a number of research guides.

You can also Google more particular research areas, such as "researching Florida law."

Additionally, you can simply go to a State's website and locate a great deal of information which may be relevant to your research, including legislative history.
