Q: When will the content of The Chicago Manual of Style Online be updated?

Technical Support Questions

Q: I can’t log in. Why not?

A: If you are a paid subscriber with an individual account, please make sure that you are entering your user name and password correctly and that the Caps Lock keyboard function is off. If the problem persists, email with a description of your problem.

If you have subscribed as part of a group, the Account Management area located in the page footer is available only to the group administrator, who may use this portion of the site to renew and update group information. All other group members should click on their user name or use the “Log In” link, which is located at the top right-hand corner of each page, to access the contents of The Chicago Manual of Style.

Institutional patrons and free-trial users are unable to access Account Management.

Q: I'm trying to log in to my individual or group subscription, but get a message that says "you are accessing CMOS via an institutional subscription." What should I do?

A: This happens when an individual subscriber accesses the internet via a subscribing institution, such as a university campus or a company VPN. Everyone logged in to the network is automatically granted access to the institution's subscription. To access an individual account from within an institutional IP range, one must log out of the institution's network and then use individual credentials to log in.

Q: Why do I have access to Account Management but not the protected content of the website?

A: If you are a group administrator, please note that the administrator log-in information is used only to log in to the Account Management page. All users, including the group administrator, must use the group log-in information to access the content of The Chicago Manual of Style. If your group uses the My Manual personalization features, the administrator must occupy a spot on the member list and create an individual user name and password to access the contents of the Manual.

Q: I’m using Internet Explorer in Mac OS. Why do all the columns and tables look funny?

A: The supported browsers for this website are listed on the Recommended Browsers page.
