It's kind of hard to place this at second, only just, because it is an online library of pretty much everything thats been writen on rock, EVER.
It's an incredible online resource set up by Barry Hoskyns on 2000, containing 12,000 articles from Creem, Rolling Stone, Melody Maker, NME, Crawdaddy, Mojo, Billboard, Kerrang, etc
You can browse by journalist, by artists, by magazine, putting your hands most of what you would need as an avid fan or professional writer/presenter. There;s also heaps of audio interviews which are a fascinating gate into the history of rock............
It works on a subcription rate of only $A60 per year so is probably cheaper than all the magazines you would buy in this time..........check it out !
