After a rule/regulation is proposed and subsequently adopted, it is codified within the Illinois Administrative Code, which is a subject compilation of all codified rules/regulations promulgated by agencies within the state of Illinois. All rules/regulations for a particular state agency are codified under the same title, but subdivided into many parts and sections.
The Illinois Administrative Code is available online from various sources. However, there is no official online or print version.
The Illinois Register is published weekly by the Secretary of State and contains proposed and adopted rules of Illinois state agencies.
While the online version of the Illinois Administrative Code is not considered official, it is kept very up-to-date and can be used to identify recent changes to a code section.
The revision date can be found at the end of the code section. Example: at the end of Ill. Admin. Code tit. 32, §33.20 (2016) you would see: (Source: Amended at 32 Ill. Reg. 9247, effective June 13, 2008).

Note: Since the Illinois Administrative Code is updated so quickly online, you may find that the change listed in the Sections Affected Index has already been incorporated into the text of the code section.
It is still imperative that you always update the code section to be sure you are aware of any recent changes.
Locating state agency decisions is not always easy. Some agencies provide decisions and orders on their websites. Sometimes these are searchable, but at other times specific information may be needed to locate the materials (e.g., a case name or docket number).
The list below is a non-exhaustive list of state agencies. The availability of decisions on its website, and/or on Lexis or Westlaw, is indicated for each agency. (Bloomberg's collection of agency materials is not as extensive. Click on the Illinois scope note under "State Regulatory and Administrative" for more information.)
