Library Account & Renewals

Can't access your library account? 
We recently switched to a new library system and some users have been unable to login.
Please read more for updates, we've made changes.
 

Update - June 23, 2022

We have made some changes to the backend of our authentication service that should resolve the library account login issues. Before contacting the library, please follow these steps:

  1. Clear your web browser's cache
  2. Login to Omni using your MacID@mcmaster.ca and Password (if you are a current student, faculty, or staff member)
  3. Do you need to renew a book? Unfortunately, this feature isn't working right now. 
    Please connect with library@mcmaster.ca and we can renew items for you. 

If you are still unable to log in to Omni, please contact library@mcmaster.ca and send us any error messages.

We're sorry for the inconvenience.  We appreciate your patience and understanding.
