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.


McMaster University Libraries' Institutional Repository, MacSphere, is currently only available to on-campus users and users connected to the campus VPN. The libraries' Digital Experience unit continues to investigate and will update this service disruption notice.

Sorry for any inconveniences caused and thank you for your understanding.
