This is beyond awesome!
Blogger Cthulhuchick constructed an eBook containing all of H. P. Lovecraft‘s short-stories and books. All of his works are now in the public domain so this is indeed legal to download to your computer.
There are multiple formats available and she even made a page that explains the installation for various devices.
I’ve already installed the book on my iPhone (the epub format works perfectly with Apple’s iBooks App) and will now re-read all of those amazing stories.
