There’s a corner of the popular Discogs website dedicated to books, and it looks like there’s a lot of music books posted (Rip it Up and Start Again: Postpunk 1978-1984 sounds interesting). Besides combing through book listings, you can search for ‘zines there, and you’ll see entries like Anti-Zine and This ‘Zine Sucks and Nihilistic Holocaust and Putrid Dysentery, and that’s just on page one of the results.
You could also search for fanzines, and you’ll get results like Mutilated News and Bestial Desecration and Yuk! and Dog Eat Robot. So whatcha waiting for?
