Public printing will be unavailable from 3pm-5pm Friday July 25th in order to perform a software update.


On July 23, 2025, the Libraries' Digital Experience team will perform planned maintenance work on the libraries' servers, starting at 7:00 am and ending at 9:00 am. The maintenance work will focus on applying general system updates. During the maintenance window, there will be some interruptions - and, at most, two outages - to the libraries' many public-facing systems, including the library website.

Omni and off-campus access, however, will not be affected during the maintenance period.

Thank you for your understanding and apologies for any inconvenience caused.


McMaster University Technology Services have a planned network maintenance window for Saturday, July 12, between 8:00 am and 12:00 pm. The planned work is expected to last between 30-60 minutes. The library website and other library web properties and systems will be impacted; disruptions and outages are expected.

Off-campus access and the Omni library catalogue will not be affected, however.
