Researching History Online

The history of all regulations since 2007 and some from 2006 can be located in the online version of the Code of Colorado Regulations. Researchers can view some of the history of a regulation in the current regulation from the Editor's Notes, which follow the text of the regulation. For earlier versions, the researcher will need to click on "I need older rules" when using the search interface.


The link provides instructions and a further link. 


The researcher will need to enter the regulation under "Name" and then also select "Rules Title Pages" under "Licensing Document Category / Type" in order to retreive the older title pages.​


The researcher can then pull up the title's pages by clicking the first link in the resulting table of results.


The title page can be viewed online or opened in a pdf viewer.
