The UK Zine library blog is an excellent online archive of punk and DIY zines from the late 70s to early 90s. Much of its content takes in the UK anarchist punk zines so relevant to the early days of Napalm Death and there are plenty of mentions of Napalm as well as Godflesh and Bolt Thrower throughout the archive.  Go here to view the archive http://ukzinelibrary.blogspot.com/
