“Our total book count is, last I heard, 62,270,” McKnight says. “At one point, our goal was to collect all the science fiction that had ever been published. But with the rise of self-published science fiction, that’s not even sort of possible anymore.”

Still, MITSFS (pronounced “MITS-fiss”) maintains what is believed to be the world’s largest open-shelf collection of science fiction. The Society strives to acquire every new science fiction publication for its collection, sometimes obtaining proofs before a book is officially published.
