There are absolute huge numbers of very tiny run magazines that simply no longer exist in any form, and the people who even knew about them may be old or dead.

Think "college-adjacent" run off the mimeograph machine late at night kind of thing. They could have run for 4 years or more, and basically be forgotten.

Now and then you hear of a famous author's work being rediscovered in one, from something they wrote in college for one of those magazines.
