Given that the first literary journal was published in 1663, the year that an anonymous drama with the wordy, if not worthy, title of The Wandering Whores' Complaint for Want of Trading was published and Moliere released his La Critique de l'école des femmes, it would be fair to also canvass the appearance of magazines in books. That is, if we hadn't said nothing but dust jacket a couple of posts ago.
Opinions as to the worst literary magazine are unfair to n+1 if I don't know what n+1 are saying.

The School Magazine is the longest running literary magazine, turning a hundred in 2015.

NewPages mentions that Little Star is nearly four hundred pages long.

It's of little import whether John Spencer was producing work at the time the literary magazine made its first appearance since it is now clear that these publications publish poetry and short stories themselves and need not allude to books, or can mention them in passing.
Though who can say what the ripple effect is at any one time?
