The seventeenth edition of The Chicago Manual of Style reflects both technological advances and enduring standards in writing and publishing. It addresses modern digital practices, including electronic workflows, metadata, citation tools, and the growing range of electronic sources such as social media and apps. Updates support self-publishing, open access, and Creative Commons models, while also improving guidance on DOIs, timestamps, and e-book references. Beyond tech, the edition enhances grammar, syntax, and usage guidance, emphasizes gender-neutral and bias-free language, and reorganizes key sections for better clarity and navigation. The bibliography has also been expanded with current, high-quality resources.
