In addition to The Chicago Manual of Style, PerfectIt has built-in styles for European Union Style, United Nations Style, Australian Government Style, GPO Style, American Legal Style and WHO Style. If there are other manuals that you’d like to see in PerfectIt, we recommend reaching out to their authors/publishers and letting them know. In the meantime, you can customize style sheets to adhere to guidance from any style manual. You can learn more about customizing style sheets in our video tutorials.
