Eighteen years ago, in one of the most anticipated moments in American television history, fans of “Seinfeld” obsessed over the series ending its nine-season run and struggled with saying goodbye to one of the most influential, hilarious and successful comedies of all time.

In a sense, though, the farewell wasn’t entirely necessary.

The show has lived on in perpetuity, with reruns broadcast daily in almost every corner of the U.S. And, in fits and spurts, we’ve been satiated with extensions of the show and glimpses into the making of it.

Jerry Seinfeld resumed his stand-up life, regularly giving audiences a chance to ask questions about the show, and started “Comedians in Cars Getting Coffee,” which has included appearances by “Seinfeld” co-creator Larry David and co-stars Michael Richards and Julia Louis-Dreyfus. David gave birth to a series, “Curb Your Enthusiasm,” made of pure “Seinfeld” DNA, and even built a season around a reunion of the earlier show.

Even though the show has never really gone away, we still crave more. The proliferation of so much material likely complicates an author’s ability to add something new to the conversation, though, and despite her noble efforts in “Seinfeldia,” Jennifer Keishin Armstrong does little to broaden perspective on the show for its most ardent fans.

Though Armstrong spoke to numerous writers and others involved in “Seinfeld,” the new light they shed is limited. The book did not include fresh conversations with the main characters or David, relying instead on other published comments and the aforementioned litany of easily available sources. Without key players, we’re given discussions on the periphery: with the real-life Kramer, the theme song’s composer, the woman whose face adorned a movie poster for the in-show movie “Rochelle, Rochelle.” Not that there’s anything wrong with that. But you wonder why we couldn’t come away with juicier morsels from more of the many hundreds involved in the show.

Couldn’t the author even track down more members of the fascinating parade of ancillary characters who might offer some new stories? Not Jerry Stiller, who played George Costanza’s father? Not Wayne Knight, of Newman fame? Not the actors behind David Puddy or J. Peterman or Susan Ross?

Interesting threads are not completely missing from “Seinfeldia.” We learn of a scrapped episode in which Elaine weighed buying a handgun, of Richards’ aloofness on the set and of a York Peppermint Pattie standing in as the famed airborne Junior Mint to make sure the camera could easily track it.

Those glimpses are few. Deep into the book, in a chapter examining whether a “Seinfeld” curse doomed the cast from replicating their success, you’ll find a telling quote from Jason Alexander. The presence of a curse has easily been dispelled by the successes of “Veep,” “Curb” and “Comedians in Cars,” but Alexander’s words could easily apply to Armstrong’s attempt. “The problem with Seinfeld,” he says, “is that measuring up is no easy standard.”
