To continue my love letter to all the enthusiasts of the world that litter the web with their obsessions, may I introduce you to: The War of the Worlds Book Cover Collection a site which the owner describes like this:

The War of the Worlds, by H. G. Wells, has been continuously in print for over 100 years. Collected here are the covers of many of those editions, submitted by generous fans from around the world.

All lovingly cross indexed by publisher, date, design elements and no end of other criteria. All sorts of wonders. It's a labour of love and I spent ages browsing it.
