Note: CMOS for PerfectIt is not available through our website

In August 2021, The University of Chicago Press and Intelligent Editing launched The Chicago Manual of Style for PerfectIt. Given the nature of the product and the collaboration between The University of Chicago Press and Intelligent Editing, they are unable to offer CMOS for PerfectIt to Editors Canada through our website. Members will need individual subscriptions to both products if they’d like to use the add-in.
