Monthly Archives: June 2025

Writing in June 2025, I’m in the slightly odd position of having two editing jobs to hand that require Chicago Manual of Style 17th edition (CMOS 17), even though CMOS 18 has been out for almost a year (published in September 2024). I have an online subscription to CMOS 17 and, fortunately, I thought, print copies of both books.

I was busy leafing through my CMOS 17 while editing, reminding myself of the two major changes between the two that affect me here (CMOS 18 drops the requirement for a place of publication in the bibliography, and three or more authors (not four or more) are represented by first-author, et al.)

But look:

When you are in CMOS 18 online, there is a menu option for CMOS 17, and you can flip into that (or open it in a new tab), and it’s fully searchable, just like CMOS 18 online.

And I’ve written this both to remind myself and to let anyone else know who hadn’t realise. Thank you, Chicago Manual of Style people!

This post has shared that you can still access Chicago Manual of Style 17th edition online, even though the 18th edition is now the current one.
