The central branch is located at the Paul Martin Sr. Building on Ouellette Avenue in downtown Windsor.

On July 25, 1900 a formal request was placed to Andrew Carnegie to help establish a new library which would be up to date and would have the means to accommodate the people of Windsor.

[3] A CA$20,000 donation was received and a site was selected to begin the process of erecting Windsor's new library.

[1] Once construction began, it became clear that $20,000 was not a large enough budget and in June and July 1902, Mr. Carnegie took it upon himself to give a further $7,000 towards the project.

[4] The quality of service that the Carnegie Library was able to offer was dwindling but the city was unable to make a change in location at this point.

[7] It was at this time in the mid 1960s that the Library Board made the decision that a new building was required in the post-war period and the citizens of Windsor heavily supported this idea.
