The Way We Were ...
Construction of the McLean Centre for Collaborative Discovery (MCCD), the building which will house the new Innis Library and several other services, is entering its next phase of development. There is the potential for additional noise between August 2023 and February 2024 as the steel frame is erected. For more information, see this alert.

The business library will be on the third floor of the new McLean Centre for Collaborative Discovery (MCCD).
March 2025 - Vivian Lewis (left), associate vice-president and university librarian, and Ann Pearce, manager of Innis Library, are excited to welcome the McMaster community into the new Innis Library.
After being closed for nearly five years, the long-anticipated return of Innis Library is on the horizon.
Innis, McMaster’s business library, closed its doors in March 2020 in preparation for demolition and the construction of the McLean Centre for Collaborative Discovery. The library, slated to open in fall 2025, will be housed on the third floor of the newly constructed 10-storey building.
Lynne Serviss, associate university librarian, User Services and Community Engagement, says visitors of the new Innis Library can expect to see a modern design in the space.
“You can almost describe it as a boutique kind of style,” said Serviss. “It’ll have group study rooms, individual study space and collaborative space. It will have all of the same services that are offered in all of our libraries, nicely packaged on a compact, state-of-the-art footprint.”
Innis Library will feature 10 bookable group study rooms, quiet study space, public PC computers and stations to connect laptops to larger monitors. The bright, window-lined space will have a mixture of couch and desk seating as well as high-top chairs sitting at a table along a wall of windows. In the stacks, students will find print materials relating to business.
Ines Perkovic, business librarian at McMaster University Libraries, says the reopening of Innis Library will have a positive impact on students in the DeGroote School of Business.
“We have been working hard to continue supporting business students during the closure of Innis and are so excited to welcome them into a brand-new space in the fall,” Perkovic said. “Having a space where commerce students can collaborate with each other and obtain resources related to their studies is going to be a valuable asset to the faculty.”
Until Innis Library opens, students enrolled in the DeGroote School of Business are supported online and in-person at Mills Memorial Library. For more information, please email the library or visit the Innis Library webpage.
UPDATE: The McLean Centre for Collaborative Discovery is now expected to open Fall 2026.
Innis Library (circa 2014), located on the north side of campus in Kenneth Taylor Hall (KTH-108)
In the late 1960s, when the plans for the Arts III building were being finalized, it was decided that the new home for the Faculties of Anthropology, Business, Economics, Political Science and Sociology would also include a study space for the students in those Faculties.
In 1971 when the newly dubbed Kenneth Taylor Hall opened to the campus community its new study hall featured seating for about 90 students as well as a caged area that housed reserve material for courses offered by the various Faculties. Materials would be accessible only for a few hours a day, courtesy of a temporarily transplanted staff member from Mills Memorial Library.
This new space was named after Harold Innis, famed economist, communication theorist and McMaster alumnus. The Innis Room was quickly embraced by students from the moment it opened its doors.
The heaviest users of the Innis Room were from the Faculty of Business. To stay competitive with business programs at other universities, McMaster pursued accreditation. One of the requirements for this level of certification was to have a dedicated business library.
In the fall of 1973, after much deliberation and negotiation with the adjoining Faculties, it was decided that the Innis Room would become known as a business library. A full-time librarian was hired and plans for the transition began to take shape.
In the early summer of 1974, the Innis Room was closed so that the reserve cage could be removed. Books, shelves and furniture were also transferred from Mills Library.
On July 2, 1974 the Innis Room officially re-opened as a business library and soon boasted over 5,000 reserve items. Despite its modest size, the space saw approximately 180,000 people pass through its turnstiles in its first year of operation.
Traffic at Innis continued to grow at a steady pace throughout the seventies and into the eighties. By the end of that decade, it had become quite clear that overcrowding had become a problem, exacerbated by the steady growth of its book and periodical collections.
By the early nineties, when construction began on the DeGroote School of Business building, a major expansion and renovation of Innis was integrated into the plan, eventually more than doubling its floor space and seating capacity and most symbolically, changing its designation from “Room” to “Library”.
Over the decades, microfilm and print have slowly been usurped by the proliferation of online databases which provide access to countless reports and articles in thousands of periodicals. Despite the changes in technology and access to information, the needs of McMaster’s business and commerce students remain very similar to those of the early seventies; to find reliable and relevant information, quickly and efficiently.
Innis Library has proudly been taking care of business for 40 years and will continue to strive for new and innovative ways to serve its users.

ADDENDUM: Innis Library closed on March 19, 2020, but will reopen in a few years when the DeGroote School of Business building expansion is completed. Until then, library service and support for business will be delivered out of Mills Memorial Library.
