Illinois bills and laws are available from the Illinois General Assembly.

Illinois regulations are announced in the Illinois Register and compiled in the Illinois Administrative Code by the Secretary of State Indexing Department. The Illinois Register are available online, but the Illinois Administrative Code is not.
The easiest way to find this information is to look on your voter registration card. Both congressional and legislative districts are listed there. However, if you can't find your card or you want to know who represents another district, there are a couple of places you can look.
The Illinois State Board of Elections has a searchable database to help you locate representatives based on street address. The search results include links to contact information for each representative, including all of their district offices. However, sometimes the search engine has problems with some street addresses. In addition, it will not accept a five-digit ZIP code if you don't have an accurate street address. You can work around this problem by searching the U.S. Postal Service's ZIP+4 Lookup to get a nine-digit ZIP code.
The Illinois Civil Justice League also has a very nice district locator. Their service provides links to representatives of all districts within a five-digit ZIP code, which is an issue in larger cities like Chicago. They also offer the ability to search for a nine-digit ZIP code without leaving the web site. In addition, they offer links to federal elected officials from the results page. Other features include the ability to write to legislators, congressional representatives, and other elected officials directly from the web and to access comprehensive information about each official's campaign finances.
The Environmental Defense Fund's Scorecard site produces local reports by combining scientific, geographical, technical, and legal information from over 150 electronic databases. Local reports include contact information for legislators and decision makers. Another good source is U.S. EPA's Envirofacts page. It's a single point of access for environmental data collected by the agency. EPA also offers a "search by zip code" feature on their Your Community page.
