Hello, and thank you for your ask. First, my apologies for excessive delay.

Second, while I have yet to lay hands on a copy of any of the Siren periodicals myself, I have heard of it ... a cursory search of Worldcat shows that there are a few libraries in the USA (University of Wisconsin in Madison, WI, the Ohio State Library in Columbus, OH, and the Cornell University Library in Ithaca, NY) that may have copies of that magazine in their archives. Otherwise, it appears there are a number of Canadian libraries that have copies. See the details here. A Yale University guide from 2005 also claims to have a few of the magazines (See here.)

Worldcat is a pretty good resource, but of course it often doesn't capture the potential catalogue of every archive out there. If you are looking for in-person copies, I'd recommend studying a map of your area to see what colleges and libraries that might conveniently be in your area, and then perusing the internet for any associated websites these libraries and colleges might have. With any luck, they may have an online record listing their current archival contents. Any library or archive with a dedicated LGBT+ section might show promise ... and you can always ask that same archive if they know of any other archive with copies, if they themselves lack copies of the Siren magazine. (I would go for college archives first, personally.)

Going off wild guess, I would assume that within the USA, the best chances of finding a physical copy might lie with archives relatively close to Toronto, Canada, as that was where the magazine was originally published. State-wise, Toronto's closest neighbors are Wisconsin, Michigan, Ohio, Pennsylvania, and New York. I wouldn't be surprised if Chicago, Illinois has something ... I love the libraries over there, quite extensive.
